The apartment is located perfectly, very close to the center and just 7 min by walk to the museum quarter (which was my main destination). Another huge plus is a cozy and really sunny balcony, so you can organize a nice breakfast there. I think it is the best place in the flat.
Ckonny was a very nice host, she wrote a long instruction of house-rules and tips, that helped me a lot. My special thank you for coffee capsules and milk in the "Airbnb breakfast", it was very cute.
At the same time, for me, this offer is not the best value for money since for this price you can find a pretty nice hotel. There is no living room in the flat only bedroom, so you can relax only in bed (or on the balcony which is the perfect place for it!). But this is just from my point of view since most travelers don't come to another city to spend time in the apartment :)
