The host was super nice, we helped us in whatever he could and explained us everything about Porto, including nice restaurants and excursions.
The place is really clean and cosy, as we could see in the pictures. However, the fact that we could not completely open the windows as we were in a low floor was a drawback. The position is okay, a bit tiring to come back from the centre as there are loads of clims, but I guess it hapens all around the city.
I would recommend it, especially if you have not planned the trip in advance as the host is a great guide,always keeping in mind that is not a bright (sunny) place.
