We had a very nice stay at Filipe's home. The flat is in a great location, right in the heart of the Ribeira district and about as close as you can stay to the river (which was our favorite part of Porto). It was certainly comfortable enough for two, not too big but not too small. Filipe was a super host and gave us great recommendations for dining, port wine tasting, and even a path to go running. He was very responsive to all our messages and questions. We did find the flat to be a bit noisy at times - it's across from a restaurant and overlooks a patio - but we were not bothered by any noise at night. Overall we had a great stay and I'd recommend!
