When I booked João's 1234 he didn't have any customer feedback on his page. I'm glad I went ahead and booked anyway because you can't find a better host than João. He offered to give my travel party a lift into town but ended up taking us on a great tour with local food and drinks. Without ever being intrusive he was always very responsive and helpful before and during our stay and even inquired if we made it home safely. In addition to that, João takes as good a care of his apartment as he does of his guests. Everything was very neat and clean but also quite cozy and comfortable. If I ever go back to Porto I will definitely book João's 1234 again.
