My wife and I stayed at Vitor's for a few nights and we did like the place. Everything was at our service, we could get inside at any time of the night. Well, we saw photos of facilities behind curtains - no big problem at this price, especially for solo travelers.
Also we weren't bothered much by noises despite the neighborhood of a railway station.
Besides, Vitor is a very nice person, friendly and kind.
All in all, Porto is a great town.
Thank you, Vitor!
