The flat is very comfortable and well equipped with everything you could need. It is absolutely suitable for four people, the pull out couch was big enough for two to sleep comfortably. José was very friendly and helpful when you needed him and always responded quickly.
A great little grocery store and a bakery are just across the street.
The beach is beautiful and in close walking distance too. During nest-leaving season in early/mid August, the seagulls can get noisy at night. Earplugs did the trick for us.
