Chose this place for our stay in Porto stay and we're very happy! The room was very clean, the balcony was nice to enjoy a take away dinner on, the water was nice and hot, and having use of the communal kitchen was good. It is a little outside of the city's core, however, so the nearest subway is a 15ish minute walk away (if you're coming into the city by train, like we were) . That being said, there was busses that regularly leave the corner of the street that too get you downtown (or you can have a nice hike up and down the hills like we tried one night).
The neighbourhood was nice and relatively quiet, situated in more of a suburban area than the real city centre. The place service was good, and your main man for reservations was always available for questions!
Really great option for visiting Porto on a budget.
