Porto City Hosts are great. We arrived much earlier than the check-in time, but they did everything they could to accommodate us… allowing us to leave our luggage in their office and having the apartment ready much earlier than scheduled. We had a minor problem with the air-con, but their response was super quick, and the problem ended up resolving itself anyway. The location is brilliant… in the middle of the historic quarter, close to the river, restaurants, shops and popular tourist sights. Thank you Porto City Hosts!
