Our two-night stay with Cristiano in Porto was delightful! The house is very charming, with quite a history. Our bedroom was spacious, and as most everyone else has written, gifted with exquisite views out its windows. We thought the bed and pillows were comfortable, as was the private bathroom, though located on the main floor, one level down. We also had complete use of the kitchen, with its Bialetti-style coffee maker - and coffee! Every morning had a great start because of that.
Cristiano is the consummate host, attentive of your needs, and allowing guests as much privacy as they need. But he is an architect, this house is his project, and he loves talking about it with you. Or maybe I should say we loved talking about it with him. Delightful conversations!
The house is also in a great location, an easy walk to all the places we wanted to see in Porto, an extremely enjoyable city. We highly recommend a visit there, with a stay at Cristiano's historic house.
I would like to add one tip, a store in Porto called "Confeitaria Dos Clerigos", named in part because of the street it is on. It is a 5 minute walk from Cristiano's (location!), and has a sign in the window...Bifanas 1 e. That was the best Euro we spent!
