Casa Cosy is as described and pictured on this site and there is little to add to the previous justified very positive reviews.
Enrico is indeed a very attentive and flexible host doing the utmost to meet his guest's requirements. He was so kind to advise us in advance about the restauration works of the building next to the pool and provided us with sunbeds on the terrace. This did not bother us since the workers were rather quiet and the terrace is anyhow a much nicer place to hang around than the pool area. The benches with seat cushions are great and very comfortable but cannot be moved (away from or in the sun), hence a permanent set of sunbeds would be a good suggestion.
With regard to the terrace and the indeed almost incredible views: bear in mind that you get these because the building is located on a cliff, by the sea. Obviously it can be a bit windy, which is probably a blessing on the hotter days but it can prevent you from enjoying this beautiful terrace on some days in spring as happened to us. Fortunately the inside of the house is very airy and nicely decorated in fresh and light tones, which softens the regrets of not being outside.
There are a few houses offered on Airbnb in the same resort, I think Casa Cosy is in the higher price range but it is worth it. I tend to believe it is probably the best you can get there, location wise (on top), terrace and interior, both very well maintained. The inside shower is tiny, but given the layout of the bathroom this cannot be changed. But there is an outside shower as well.
Unfortunately the state of the building and the buildings around are in very bad shape and need urgent reparation and restauration. Hopefully the building works we saw are the start of it since Casa Cosy deserves to be in a better maintained building, but once inside, you forget about the rest :-)
