Claudia's place is clean, well appointed, and centrally located. Claudia met us when we arrived and gave us a tour of the apartment and provided us with lots of great tips and recommendations for the area. We especially enjoyed the keyless entry to the building and the apartment. Noise does travel a bit from the stairwell into the living area; however, it's not as noticeable in the bedroom. Overall, a lovely stay with a lovely host in Porto! Would highly recommend.
