We stayed in Porto for four days. The apartment was exactly as described and is pretty good, also for a longer stay. We did not use the kitchen, everything else worked well. The location is top, you can reach everything by foot from there. It was a bit noisy but what do you expect when you stay in the city centre ;) English communication was no problem
I recommend it! (Also, the best Paseis de Nata of Porto are made in the basement of the building, enter from other side!)
