The host ensured that it was easy for us to check-in. The apartment was spotlessly clean when we arrived and is very conveniently located to visit the main sights in Porto. There is the street noise that you would expect from this type of location. With the entry system in place at the block and as the flat is located on the top floor it felt very secure.
The balconies were great for us as adults but due to the height of the guard rails I wouldn't take children to stay here.
