Had a very enjoyable stay at Christa's. I stayed for 4 weeks and would do it again if i had to travel to berlin. The host is reliable and easy to communicate with in german and maybe also in other laguages but i don't know that for sure. I received fresh towles and bedsheet upon arrival and was able to do laundry whenever necessary. Bike storage in the basement was a welcome amenity. The bathroom and kitchen could've been cleaner for my taste but it was nothing that you should be too concerned about.
