One of the best appartements I have been in Porto as for once I nearly felt at home.
The appartement is in a quite pedestrian street, so it's peaceful and perfect to rest.
The living room is great and has a view on some kind of courtyard with trees.
There are 2 bedrooms and a bathroom (Shower) on the same level and there is an additional bedroom in the mezzanine. Yet please beware of the steep stairs.
