We had a lovely stay in this nicely renovated building. We loved the combination of modern rooms in combination with the old walls. The place isn't in the center but it's just a small walk away. Not too far away from the metro either, so easily reachable from the airport.
Big recommendation for the lady that did our check-in. We came to Porto with no clue on what to visit as it was planned last-minute but she gave us an extremely detailed plan on what we could be doing during our stay. We immediately knew what to do and the suggestions were on point!
