I highly recommend the place. Very comfortable, clean and the host is very nice and easy going.
The location is excellent with João de Deus metro station 5 minutes walk, a very good restaurant and take away around the corner as well as a supermarket.
You are surrounded by cafés, patisseries and El Corte Ingles.
The metro takes you to Oporto in 10 minutes although it is a pleasant 20 minutes walk down the avenue over the bridge to downtown.
