Very nice space with 2 large balconies, each with a good view. Communication with owners was flawless. It is up several flights of stairs, so make sure you can accomplish that if you book. If you aren't able to cover a lot of elevation on foot, you aren't going to be able to enjoy Porto much anyway.
It's in a little bit of a transitional neighborhood (which seems to describe most of Porto), so be ready for the short walk on a narrow winding path to the unit entrance.
