Overall we enjoyed our stay here, the owner was most helpful with very useful ideas and tips to experience Porto, it's sights and restaurants. She was also responsive when domestic issues needed attention. Beds were comfortable and the area fairly quiet except for Saturday night.
The terrace that appears attractive in the promo might be that in mid Summer but is situated at ground level with 3 levels of building on all sides. So it was cold, dark and damp with no sun at all by early October, despite Porto still being quite warm. We didn't use the area all week despite temperatures in the mid 20s (C).
The apartment had a few annoying features that the owner should address, some due to poor build /workmanship and others, design, that you'd not expect in this price bracket.
We could not lock either bathroom/toilet door, they tended to slide open so we ended up resorting to wedges for privacy.
Lighting in the kitchen / meals area is very restricted. There is no lighting along one main wall and the opposite wall only has down lights making any kitchen activity difficult. Better lighting should be installed.
The only window in this area opens out directly on the street so passers-by tend to look straight in if opened for ventilation. This window is shuttered but these are broken and difficult to close, as one must do for security.
None of these is insurmountable so hopefully fixing will make this an even more enjoyable place to stay.
