The apartment has an amazing location, directly at the city center. Really top location. Heating system is with air conditioner. Unfortunately in the second bedroom was a pipe which was not sealed up. That is really not ok. The wind is blowing trough this pipe like a open window. In January this situation is not a option and not necessary. Especially when you woke up in the middle of the night because you are freezing.
Host was very nice gave us a late check out which was very helpful.
