Mario was always quick to respond to our messages and offer up his time for our questions. The place is in a wonderfully central location which made it easy to navigate the city and see everything we wanted to see during our short trip. Be advised that because of the location there is a lot of noise in the area. We were not bothered because we enjoy being in the middle of everything, but it can get loud. We loved Porto and would definitely stay at this location again if we ever return.
