The stay was okay overall.
Unfortunately, the pictures in the ad do not all correspond to the rented apartment. (The rest of the pictures must be from the other apartments that David also rents).
Also, the apartment didn't seem to have been really cleaned. One or two problems during the stay we had raised and unfortunately got no answer.
What we liked was the location of the apartment. You are super fast in the city center, but still has its peace. The building as such is a beautiful old building. David is nice and very helpful. We would recommend the apartment, provided you can put up with the above points.
