This is an amazing apartment in a beautiful city. The location cannot be overstated - it's close to everything (train station, riverfront, tour buses, livraria lello, I could go on...). As others mentioned, the only consideration is the walk up 5 flights of stairs to get to the apartment. That said, Porto is a pretty hilly city, and by end of the day we thought, "well, what are 5 more flights anyway?". Apartment was clean and spacious with a homemade guide book that was much appreciated. Paula, Raquel, and Martha are all very responsive and helpful. My father left a print behind, and they even made sure to mail it back us! Highly recommend!!
