We had a very nice stay in Casalabate.
The beach is just 2minutes walk away. There are supermarkets about 7minutes away. The apartment is like on the fotos, plus there is a extra-shower on the outside of the house :) . The house is well-equipped, everything was fine.
I would recommend to rent a car, so you can easily visit Lecce (which is a beautiful town and near by) and drive around the coast too....
The host was super friendly and helpful, (since WE had some problems to get our rental car :/) and was always able to contact. Thanks a lot again!
