We were traveling around Portugal for 5 weeks and been to many places. We must say this place was one of the best in terms of location and atmosphere, moreover the room was soooo spacious! Traveling with a small child 7 months old we could easily fit with all our belongings.
Location is in the heart of Ribeira, just at the riverfront - you open the window and you are there, with amazing view at the other side with all Porto wine brands gleaming in the evening. With all bars and restaurant nearby we could leave the baby asleep and go out with electronic nanny.
It is a walking distance to majority of attractions in Porto, though pretty steep walk up. Still you can always take a bus or a lift up that is just in front of the bridge.
We were afraid to be a little noisy place for a baby, however busy during the day it turned out to be very reasonable at night and we never had any problems with sleeping.
Strong recommendation from us!
