We had a 4-night stay at Porto and just loved our apartment! It looks exactly like in the pictures, super comfy and aesthetic.
The location was great, very close to the center (5-10 mins of walking) with a lot of bars and cafés around.
The building seemed to be newly renovated, the house was clean, well-furnished, and well-equipped.
The only drawback was that the windows were not soundproof, and it got very noisy at night and especially on Fridays when the youth were outside the bars and cafés.
