We loved staying at Rafaela and Celio's place. It was spacious enough, very clean and right in the middle of Porto, ideal for travellers who don't spend a lot of time in their accommodation but want to be comfortable after a long day of walking around. Rafaela greeted us with some port and was willing to answer all our questions about the city, what to do and what to see whilst in town. We would definitely come back to Ai Porto if ever back in the city!
