Marta was a fantastic host! Very welcoming and hospitable, contact was really fast and easy, and Marta speaks English really well. She provided us with maps at the apartment and told us about things to do in Porto.
The apartment was comfortable for 4 people (one bedroom and a nice sofa bed in the lounge). It is compact but feels spacious enough. It is a close walk to the centre city. The apartment also has Wifi (including a portable router), speakers and an espresso machine. I would happily stay here again.
