Cristina was very welcoming and was able to provide a lot of great advice on where to go/what to do in Porto. The apartment was in a fabulous location, very close to the Douro river and all of the restaurants and shops. The apartment was spacious and was well equipped, the only negative thing was that all of our close felt damp while staying there. Overall I would definitely recommend staying at Carlos and Cristina's as it is in an amazing location!
