A couple of minor things to note from the hotel description; They do not operate an airport shuttle bus, and there is no car parking on site. However, there is plenty of parking in the vicinity of the hotel. The hotel itself is absolutely perfect as far as I am concerned. It is small enough as to never seem overcrowded, even at full capacity. The rooms are spacious and very clean. Also, the bed was probably the most comfortable I've slept in when away from home. As for the staff, they are attentive and helpful.

I would not agree with the hotel having 5 stars, I think it is a proper 4 star hotel. They lie about having a gym and a sauna: the gym is a 3x3 meters room that has 2 machines and that is it, useless to be honest, while the sauna is only accessible if you take a massage, which costs 80-500 eur depending on the massage. If you want to make use of a gym and a sauna during your vacation, this hotel does not have that option. In addition, our first night we did not have blinds in our room, so we woke up 6AM with the sun in our faces. During the first 4 nights the A/C in the room was not working properly and restarting to 28 degrees every approx 1 hour, so you woke up sweating every few minutes. They fixed this however after a few days when many guests complained. Everything else works fine, but I would not return, since it makes much more sense to go to a 4-star hotel that is priced as a 4-star hotel and has the amenities that it says it has.

L’hôtel (resort) est divisé en plusieurs bâtiments qui sont assez proches les uns des autres. Celui où nous avons séjourné était le plus ancien et sûrement le moins refait. Premier problème le coffre de la chambre qui se bloque … rien de grave mais au retour du restaurant plus de clim dans la chambre … 30 degrés. Appel à la réception puis au bout de 15min d’attente je descends voir le réceptionniste qui me dit que tout est ok mais non rien n’est ok. bref 10min plus tard le technicien arrive bloqué la clim sur froid et repart. Le lendemain de l’eau partout sur le sol, des gouttes qui perlent sur le spot du plafond … Confort général assez simple et décoration basique sans charme ni design. Le tout décevant malgré la sympathie du personnel.

Ik heb over het algemeen een prettig verblijf gehad in dit hotel. De kamers waren schoon, het personeel was vriendelijk en behulpzaam en de Griekse medewerkers waren gastvrij. De ligging is mooi en het hotel heeft een rustige uitstraling. Helaas heb ik ook twee vervelende ervaringen gehad met andere hotelgasten. Op een avond zat ik op mijn balkon te eten. De balkons hadden glazen afscheidingen. Een hotelgast op het balkon onder en naast mijn kamer ging op de plantenrand van zijn balkon staan en bleef rechtstreeks door de glazen afscheiding naar mijn balkon kijken terwijl ik aan het eten was. Toen ik hem opmerkte en aankeek, stapte hij direct van de plantenrand af en liep terug naar zijn kamer. Bij een andere gelegenheid bleef een andere hotelgast mij in de avond langdurig aankijken en maakte hij een gebaar dat ik opvatte als een uitnodiging om naar zijn kamer te komen. De Griekse mensen die ik heb ontmoet waren vriendelijk en gastvrij. Mijn persoonlijke indruk was echter dat de omgeving voor alleen reizende vrouwen minder geschikt is. Dat is mijn eigen ervaring en anderen kunnen dat natuurlijk anders beleven. Ondanks deze gebeurtenissen heb ik genoten van mijn vakantie, de mooie omgeving en de goede service van het hotel. Ik hoop dat het hotel aandacht blijft houden voor een respectvolle en prettige sfeer voor alle gasten!

Bel hôtel mais on trouve beaucoup mieux en Crete

Attention le descriptif des équipements de la chambre est trompeur il n’y a pas de bain à remous extérieur dans la supérieure vue jardin contrairement à ce qui est écrit et le stationnement se fait dans la rue. Le restaurant est délicieux et le personnel sympathique mais les avantages Vip n’ont pas été pris en compte même pas le départ tardif de 2h qui est normalement garanti. L’hotel est beau mais les finissions à revoir pour un 5 étoiles. Literie excellente. Environnement proche moche. Voiture indispensable.

OK hotel

Ons verblijf was OK. Ook niet meer dan dat. Check in was vriendelijk en vlot. Helaas kamer nog niet klaar half uur voor check in tijd, maar dat is opgelost met een welkomstdrankje. Het hotel is netjes, maar kaal en kil. De kamer is netjes, maar erg basic. Het bed is wel erg zacht, maar dat bleek ook redelijk versleten. De TV is best verouderd. Internet heeft een aantal pogingen nodig om in te loggen. Dit hotel is echt geen 5 sterren waard. Prima 3 sterren hotel!

Nice Hotel but obviously Covid is still restricting staff levels. Room comfortable but not as described on Hotels.com. Room did not have hot tub which was in the description. Only got 2 small bottles of water on first day. Had to keep asking for cups/t-bags. Cleaning not great and no towels on 2 days. Other guests in hotel were returning customers and they were disappointed with the changes/issues. Would return to the area again but not that hotel. At the moment it is not 5* as advertised

Outstanding experience

Big spacious room with great view, perfectly equipped with both shower and massage bath tub. We could not ask for more! Staff was extremely helpful and very kind. Despite corona virus outbreak, service was not affected - I would say that being served exclusively by staff is even better than having access to buffet. Food and drinks were simply delicious - just like you would expect from a 5* hotel. Very quiet location, not overly touristy like other locations we visited. We are looking forward to visit this hotel in a future!

Be aware before you book

We booked a suite with private pool thinking that the price and reviews made it sound like a 5 star experience. It came very highly rated, which is very surprising and makes the whole peer review exercise unreliable for future bookings. Our room was really in terrible condition. The pictures do not show how much wear and tear the hotel is under. The blue couch in our room was marked with brown from dirt and the towels had holes in them (see photos). Not to mention that the floors had the grout scrubbed white but the rest of the tiles they did not clean... The staff was kind and apologetic but there is nothing they can do. Just beware when you book not to pay a premium which is non refundable... Other rooms may be better and are much cheaper. The pool is nice. The dinner is not to our taste (we prefer the local Taverna food) but included in the rate, so a cheaper solution. Their COVID sanitation is likely to standards. I left and felt cheated and disappointed. Luckily we booked for one night and left for a luxury five star hotel at the same price.
