The apartment is new and super clean. I felt very comfortable and safe there. The location is not too much close to the city centre, but the good news is that it is a quiet neighbourhood. Uber is affordable and I spent around €4 euros to get to Ponte Luis and €12 euros to get to airport, for example. The host is super nice and quick to respond, I was able to leave my luggage in their office and explore the city hands-free before check-in. I highly recommend this apartment and Porto is an amazing city to visit. Thanks !
