We had a great 5 night stay here - the location is perfect - fairly quiet (perfect for us with a 2 year old) but very safe feeling with easy access to the centre of Porto. The only thing I would make people aware of was the stairs to the apartment (2 floors) which might be difficult for some with small children. But as we were only leaving once in the morning and returning at night it was no big issue. Would definitely stay here again.
