We stayed for four nights in Ana's apartment and we had a wonderful time. The place is even better than it is shown in the pictures with everything we as a couple needed. The location is very central and right around Aliados metro station. There is no elevator but we had no problem using some stairs as it's on the 1st floor. Ana is very quick and easy to communicate, gave us many useful information, and even allowed us to keep the luggage for some hours after we check out. Overall it was a pleasant experience and definitely want to stay again if we come back to Porto.
