You will enjoy your stay at this lovely and well appointed apartment right next to the river. It's not that far from the historic part of town and the trains and buses are right at your doorstep. The apartment is 40 steps up from the street. It's a bit of a climb to get up to it, but once you're home, you'll love the ambiance. It's pretty quiet for where it is and the view of the river is nice.
The Lelly bookstore, train station and the famous tower are way up the hill. We found out that a taxi or Uber were cheaper than two bus tickets and much easier to navigate. Porto is very hilly. Walk up and down if you dare. It's quite a climb.
