The communication with the host was perfect, and she was very flexible in our arrival time. The location is very central with a lot of bars and restaurants in the neighbourhood. This leads to some noise during the nights in the weekend, but you can close the windows as AC is present in the apartment.
The apartment was clean (almost sterile) and everything needed is there. So perfect for a weekend in Porto. However if you are looking for a cosy apartment you might want to look a little further.
