Listing was in a perfect central location, with evening music entertainment right nearby, plenty of restaurants and coffee shops all within a 10 minute walk.
The noise of the street performers was quite loud at times but it always finished at a reasonable hour. (Between 22:30 and 23:30)
The apartment is not very soundproof so you can hear neighbors upstairs and passers by on the street however the features of the apartment more than make up for this. But it's not perfect for anybody looking for a quiet get away.
The apartment was very homely and exceptionally comfortable, a really lovely stay with towels, soaps and other things provided.
Absolutely would recommend to anybody staying in Porto and looking to explore the historical city.
