Good points:
A cozy, airly land-view site. A beautiful church locates 7min by walk, and a grocery store next to the church. You can find many local, distinctive foods there (roads towards the church & shop is also beautiful and rural-typical looks).
A pool locates 1st floor was open 9:00-19:00, with confortable chairs. Best to spend a relax time after breakfast.
Drawbacks:
In terms of surrounding area (and shops), owners didn't provide information enough. By chance, I found a cozy restraunt (approx. 20 min by walk. has various fresh-fish dishes) next to Lidl (German-based discount supermaket) but they didn't mention it. Just said "you can find restraurants on this way and this way" but you can hardly find restaurants nearby.
Air-conditioner was too strong. I was about to catch a cold (too hot if stopped, then difficulit to sleep). The room number was "1".
The potional 1-day tour to safari & marine, conducted by owners' chid, which they recommended was started 90mins later (10:30) and 1 hour earlier (16:00). That means it was a degraded tour. We can stopped by few sight-seeing points briefly, costs 60 euro per person.
