I'll break the review down into 3 areas - the 2nd and 3rd area is important in the overall experience as you will see, but please bear in mind that my review on the resort and facilities will very quickly become outdated
Apartment
Roy's apartment is very clean, spacious and has everything that you'll need. In fact, I think it is one of the best in the resort because it also has a private accessible roof terrace-most other apartments which have a roof terrace, cannot access them as the stairs are blocked off. Great for us as we weren't overlooked by anyone so could so a bit of all over tanning!
2 air con units were great (master bedroom and living space). Washing machine invaluable.
Roy himself was extremely helpful and answered all of our questions pre-departure.
Resort
This is where things get tricky.
The resort is predominantly an all-inclusive hotel resort but have a small amount of privately bought apartments, such as Roy's.
Because it is a new resort and because so few units are privately owned, staff really struggled with how to deal with us. There are no tills at the restaurants and bars so we had to open "an account" with our credit card at reception and then meals/drinks would be charged to our account for us to settle at the end. As it's mainly all-inclusive, there were no prices on the menus so it was very hard for us to keep a handle on how much we were spending....staff couldn't even tell us how much a beer was, and despite our "account", many of the staff still struggled with how to charge us, so every time we went to get a drink or have a meal, it was a painful and delayed process, to the point of dread, plus we were constantly worried about how much we were spending.
Reception couldn't deal with problems that we had, such as faulty door card or patio door-we had to ring someone who wasn't on site that dealt with estate issues.
Island
This is where it gets really tricky.
Despite Roy's apartment having everything we needed to self-cater, we struggled to self-cater because as everything is imported onto Sal, we found the choice of food in the supermarket extremely limited and in some cases extortionate e.g. a box of granola was about 14 euros!
Santa Maria is rapidly developing so I think in time, a bigger and better stocked supermarket will be built and therefore our concerns can be disregarded, but in the meantime, do bear this in mind!
"The Villa" restaurant - sublime
Tours - DO book in town. Pete's shack has the best deals.
