Hi,we didn't actually meet Carlos but Cristina was very kind and helpful. The apartment was very clean, in a good location and just what we was looking for. We loved Porto and its many bars and restaurants, and enjoyed visiting the port houses on the other side of the river. We found the journey from the airport to the apartment very straightforward and easy via the metro. Apartment about 10 mins walk from Sao Bento station (downhill). Would recommend visiting Porto and staying in this apartment and would like to go back one day.
