This was my best stay in Porto. I was only 1 night there but I can compare with the several times in Porto before.
The location of the apartment is 5 stars. The apartment itself is very modern- like a loft. Very spacious, comfortable bed, good shower and all you need. New windows - inside you can relax.
Mario is a good helpful host - it was a problem with the door- but he was available and helpful. I would stay here again.
