The apartment is great, with beautiful decoration, modern kitchen and comfortable beds. The location is perfect. 5 walking minutes from the Torre dos Clérigos and 10 from Ribeira. We arrived by car and during our (more than) 3 day stay, only used it once to go to a restaurant, which was far away. The street is quiet, almost without cars and there's a very genuine feel to it.
Marco and Carla were very helpful - they gave us suggestions on where to go, where to eat and asked if we needed anything halfway through our stay.
One detail about the house: the bedroom is connected to the living room/kitchen area.
It was a great place and I really recommend it!
