Excellent! Very central location, just a quick walk from the Sao Bento train station, which is perfect because the flat is located on a street that is not accessible by car. The 2 minute walk from the train station is up a short but steep hill, though, so be mindful if you have heavy luggage (as I did - but it was doable). Joao was a wonderful and quick communicator, providing easy directions to the flat as well as outstanding tips and suggestions regarding food and sightseeing. And when there was an issue with the couch, he fixed it quickly. The flat itself was very cute and very clean. I'd absolutely stay here again the next time I come to Porto!
