The accomodation is in a really great position: central, close to the transports and to the famous spots. A fantastic place if you have only a few days and want to visit the city.
The room was minimal but nice and clean, with a comfortable bed. The access is very safe, as you would need a key to access the right floor, so even if you travel alone is great!
Only down point was the noise: I could hear everything from the street and I was also very unlucky as one of the nights I was there, there was a concert 20 meters from the accomodation that lasted till 1am. Very very hard to sleep!
Overall, for the price it was really good and a strategic point to visit Porto.
