We had a pleasant stay at André's place. The house is in a central square close to many coffee places and restaurants and to one of the nicest streets in Porto. It is beautifully decorated and we had everything we needed for a short stay. The only con would be that the fridge is in the room since the kitchen is open space, and during the night you can hear the noise it makes (if you are a light sleeper as I am, would be better to have some earplugs with you, just in case). The communication with André went well before and during the stay. He sent us all the instructions to self check-in before our arrival (make sure to check this well in advance if you know that you won't have internet at the time of check in). While we couldn't do a late check out unfortunately, André was really nice and allowed us to stay a bit more (postponed the cleaning with one hour for us) and recommended us the luggage lockers in the train station, which were easy to use and reasonably priced. We really appreciated the fact that, even if the late check out was not available, he tried to help and offered a solution.
