We had a very good stay at Vlads and Kristinas flat, it was very clean and easy to find/check in. The only thing that was a bit of a pity was that the door opener didnt work, which is a little annoying when you are in the 5th floor (for food delivery and work colleagues) and the hallway was a bit scary and dirty, but I think thats just the way Berlin is :) Thanks to let us be your guests!
