We had a lovely stay at the apartment, it was clean and very well equipped, all you might need like salt, sugar, coffee, tea, iron. The reception by Hugo and his team was outstanding, they really wanted to make sure we had everything we needed, they also gave lots of suggestions for things to see and do in Porto. I would say that the only negative thing was the lack of elevator (we had a baby stroller with us) and perhaps that the apartment itself was a bit old, but I guess that is what to expect if you rent a place in the city center.
Thank you for a great stay!
