We had a really pleasant stay at Kristina’s place. The place looked like the pictures and it was very tidy when we arrived. Communication with Kristina was easy and she gave good instructions before check in, she also replied quickly to messages. Only unpleasant thing was that we had problems with warm water while having a shower, since the water became ice cold quite quickly.
Overall Charlottenburg was nice neighbourhood and there was metro stations within a walking distance from the Airbnb.
