We stayed here for 4 nights, and had a great time. The apartment is extremely well-located, quiet at night but close to everything we wanted to do. We didn't have a car for this part of our stay, so didn't have to worry about parking, and everything was very walkable.
The (historic) apartment is VERY cute — pictures show the decor well, but the layout is slightly different than we expected (you enter through the door by the bedroom, and walk through the bedroom into the living room/kitchen area, which was slightly surprising but not a problem).
The bed was very comfy. We didn't use the sofa to sleep on (the listing says this is another option) but I wouldn't recommend it — it's not long enough for a tall person and not as comfortable as the bed.
The kitchen sufficed. It's small but functional, with a very nice layout, and had everything we needed for our stay, although we mostly ate out instead of cooking. Very very cute.
Overall, a great spot. Would stay again!
