We had a great stay at Aida's haven!
Alexandra let us in, and she was very willing to tell us everything we wanted to know about Porto. Alexandra is a very sweet and caring person who seems to enjoy being a host.
The room is very nice and hip and so is the whole apartment. Every room is very nicely decorated. You have several great places to sit down and enjoy the space. The location is perfect, everything is within walking distance. The google map they offer has lots of places to visit, so follow their suggestions, they're worth it!
