We had a lovely time in Porto in Bernardo's place. If every private room we had was this private we would be very happy! Very warm welcome from Bernardo who was an excellent host. As for location, we chose to walk to downtown (roughly 40mins) Porto most days, but there is a bus literally right outside of the house that will take you straight there. Alternatively you can take the metro which was about a 15 min walk and 20 minute ride. We found street parking very easily right outside the house. The sole issue we had was the street noise, but there was construction across the street which is totally out of anyone's control. Overall it ticked all of our boxes and we had a fantastic stay in a wonderful city. Thanks!
