Perfect location!
We didn't meet personally Manuel but we had no problem in talking with him. He was really nice, as well as the cleaning lady who welcome us, and let us check-in before 15.00.
The only problem was the wifi (no internet connection) and we recommend you to have quick showers because we ran out of hot water during the 2nd shower.
The location is amazing: restaurants, bars, parks and all the "Porto must see" are nearby!
Overall, we had a great stay :)
Thank you Manuel
