Aurora and Alberto were wonderful- very helpful and such interesting people to have conversations with. At one point I felt like I don't even have to go out to see the city- could spend the whole day just talking, looking at all the amazing artwork they have there or read books from their library. The house is nicely decorated and super comfortable, the room I stayed in was just perfect. The house is just about 15 to 20 minutes walking distance from the city center,in a nice and quiet area. It's very easy to get to the airport from there, too. Alberto gave me just perfect tips of what to do, to see or where to eat in the city. I highly recommend this place if you're interested in not just having a random place where to sleep at night but also get to know the people, the city from a locals point of view and be surrounded by very special atmosphere. Also, 3 days is not enough to spend in Porto. Hope I'm coming back soon. Thank you!
