the place was really nice and clean. the only problem was that we didn't have warm water after not even 2 people showering. when we called the 24hour hotline they said they are in Lisbon and the people working at Porto only start at 2pm so we didn't get hot water. after hours when we already left to the city they replied that because we booked for 4 (we were only 3 and hat 2 quick showers) there's not enough warm water and we have to wait 1,5 hours..
otherwise everything was fine.
