My wife and I visited Porto and loved our apartment. It was just as described and the photos do not really do it justice. Sophia met us at the door and took the time to not only show us the apartment but showed us some of the best places to visit and got us oriented to the city. The map was incredibly helpful and the port that they left was delicious. All the people we interacted with in Portugal were incredibly nice!
The street was small and quaint with a bar just down the way. We enjoyed live music floating up to our window each night. I wish we had a better view out the windows but the location couldn't be beat. We were steps away from the river and a short walk to the bridge and across to Gaia. If you go to Porto be sure to visit the Duoro Valley. It was magnificent.
