It's always nice to stay at a property that the hosts actually own personally and also live in, just with a separate apartment space (and separate door) for their guests. Sophie's apartment was in that class: they live in the space just below the unit. It's not a property that's operated at a distance. The space was nice, airy, and very comfortable for 3 people. The kitchen worked well, bathroom was fine (perhaps somewhat low water pressure on the shower is all I can think to nit over.)
Location is great too; a very short walk to the Korenlei and Graslei area, but also far enough away that you don't feel like you are in a tourist dead zone. Good amenities immediately in the neighborhood as well, and easy access to two tram lines. I would absolutely stay here again, highly recommended.
