We had a great time in Maria's apartment.

First it had been a bit hard to reach her, but then she was very accomodating. We arrived in Porto before the check-in time, but Maria let us know that the apartment was ready earlier than expected so we would not have to wait. Her friend Raquel welcomed us, she was really nice and gave us great suggestions of what to do and where to dine.
The apartment is really pretty, comfortable and perfectly located.
Two negative points though : in the bedroom you can hear the neighbours (very clearly if they are on their terrace), and ours were really noisy... Also, the wifi seems to be a bit capricious.

But overall Maria is a great host and the apartment is lovely !
