We had a great time in Porto thanks to Carlos and his girlfriend. They were very nice and helpful to us, showing us places to see, to eat, and to shop.
The appartement is nicely located, in a very calm area, close to the metro (great to get to/from the train stations/airport), everything within walking distance. Everything was super nice and clean.
I would highly recommend anyone to stay in Carlos’ place to visit Porto and its surroundings.
