Marianne provided all the information we needed, and communicating with her was just fine.
The listing description was perfectly accurate. The flat is a beauty, extremely well kept, the beds are comfortable, plenty of heating if you need it. The flat is large enough to host 4 comfortably, and situated in a fantastic location. Pretty quiet, surprising given how central it is. Note you will need to walk up two floors, no elevator.
The neighborhood is lovely. We had a cool café 20 meters away, an amazing bakery 12 minutes walk, all the basic shopping you need on a radius of 300 meters, two subway lines nearby and some good restaurants and jazz clubs in the vicinity.
Makes you want to come back!
