Location: Great, you can get to the sightseeing parts of Porto by foot. The metro is right next to the apartment.
Check in: Great
Communication: Great
Hygiene: Clean. The balcony was not at its best.
Parking: We found one around the building, free of charge
Things we did not like: the mattresses are bigger than the bed frames. Sleeping is not as comfortable.
Overall review: I would recommend this place.
