We had a great stay at Gonçalos place. The communication was impeccable and Gonçales was very welcoming. He gave us a lot of local tips and recommended very good resturants, as well as bars. The space was super clean and it looked like it was renovated recently. The location is in the very heart of Bairro Alto, you basically fall out of the door right into the nearest bar. At night time the streets were packed, but the very good windows prevented most of the noise coming into our bedroom.
All in all, we loved our stay with Gonçalo and would definitely return, if we were in Lisbon again!
