We've had a lovely experience, the flat is in the center of Lisbon, very close to many great places and 10 minutes away from the sea in walking distance. Pedro sent us messages before the arrival to make sure we had all the information needed and made himself available when we had a question during our holiday. The flat was very clean et very nice, the only negative thing is that the walls are very very thin and you can ear everything your neighboor does.
Otherwise we really had a great stay !
