We spent 5 days at Silvia's apartment and in general we had a good experience. The place is pretty new and well kept. We didn't meet Silvia in person, but we were received by Beatriz, who was nice and answered all our questions. The only thing we didn't like in the apartment was that the shower drain was blocked and it was rather unpleasant.
We found the location very good for our stay. We have two small kids, so we wanted to stay near the beach. Just a few minutes on foot is the Malvarosa beach, which was perfect. And also two blocks away is the metro stop that takes you downtown very easily.
It was our first airbnb experience and we were pretty satisfied.
