Maria's apartment was wonderful; great amenities and sleeping was peaceful. The apartment was located on a very picturesque street, close to the metro, grocery store, and many nice restaurants. Maria was a wonderful host - easy and quick communication and she gave us lots of tips for sights to see and restaurants to eat and easy routes around the city...I even forgot my phone in the apartment and contacted Maria who quickly responded and happily agreed to send it back to me via the post...all in all, a wonderful trip to Porto.
