We really enjoyed our stay at her place. She has a great knowledge about the restaurants and her recommendations helped us a lot. There was no single time we regretted it, always perfect. Also the room we were staying was very cozy and comfortable, we really liked the stay in that room. Bathroom is public, but it's quite big and always clean, no problems at all. The only thing was, because it was kinda cold, at the time we were in Porto, it was a bit of torture to leave the room and go to the bathroom. But in the big picture, it was such a nice stay and would DEFINITELY RECOMMEND everyone to prefer Isabel's (Catarina's) house.
