We can highly recommend Stefania's apartment. We spent our family holiday there with 4 kids.
The apartment is very clean and spacious even for 6 people. The downtown is just a few steps away, but the beach is a bit longer walk. It is in the edge of the touristic part of the city and where the local people live.
Stefania was always very helpful with the local tips and always had a friend when we needed some service.
