The host, Pedro, was a very good communicator. The flat is about 2 blocks from a metro and on a very quiet residential street. Great location. There are small shops in the immediate area for groceries, pastries, coffee or a lite bite to eat. You can walk 5- 6 minutes to Trindade station area for numerous restaurants or connections to other metros and buses.
Very clean modern apartment, just recently renovated. It is dedicated as a rental. Lots of light. Porto is a terrific city, not nearly as intense as Lisbon. This is a great location, near a metro, for visiting Porto, but in a quiet, non-tourist neighborhood a few minutes to anywhere.
