My family and I stayed 4 nights in Maria's apartment. The apartment was very clean en nicely decorated and had perfect beds. It is situated in a great location, just a few minutes walk to the famous bridge and the old town of Porto and a minute walk to a metro-stop.
The communication with Paulo was great, quick response on our questions and he gave us good tips for our stay.
The next time we want to visit Porto we will choose this apartment again.
