I really enjoyed my stay here. It's a flat with enough space in room, great common area to chill or work or eat, equipped kitchen, and nice patios (which I would have enjoyed if I travelled in summer). It's an old building, yes, but I liked that kind of atmosphere and the feel the space gives. It's well cleaned and maintained, so no worries. One downside of my room was that it was quite loud. If you're a light sleeper, this room may not be for you. I could hear trucks and motorcycles whenever they pass by and some construction noise nearby. But I saw the room next door had an extra glass door and it was quiet. I would definitely come to this airbnb the next time I visit Porto but I'd go to another room. Also enjoyed chatting with João!
