The appartment is clean and fulfills all the requirements and is located a 10-15 min walk from the old centre. It is however located on one of the bussiest roads of Porto and since there is no air conditioning, sleeping with the windows open in the summertime is a must. Because of the traffic noise in the early morning, we did not get much sleep. Also a fun fair was right across the street, which caused a lot of noise. I do not recommend if you are looking for a quiet night.
