The room is very central in Porto and right on a street with some bars and clubs. There are many cafés and restaurant close by which was very convenient. We stayed here on a Saturday night which meant that nightlife was at it's peak.
We always sleep with the windows open so experienced a lot of noise, probably less of and issue when you close all the windows and it's not a Saturday night (+ halloween weekend). It's a perfect spot if you are planning a night out in the city and probably way less noisy under different circumstances.
The host was super kind and lend us some cutlery for some food we ordered :)
All in all, very central Airbnb, super kind host and perfect if you want a real city of Porto experience!
