I was very pleased with the communication with the host. However, during my stay I was disappointed in the lack of decent wifi, beware that this flat is in the basement and your own cellular service wont work as expected. During my stay the tv was also out of order, wasnt a deal breaker but when your in from a long day in the city a working tv is a great decompresser. The flat has most everything you need and is pleasant. The neighborhood is a little sketchy but I had no issues so if you're picky you may want to consider another location. If you're tall the bathroom is small, its a tight squeeze where the toilet is located. The flat was very clean and the instructions were east to follow to get into the flat. Keep in mind this rating is purely based on my experience during my stay only. The host was trying to get the issues resolved but was unsuccessful during my stay. Hope this helps and enjoy Berlin, its a lovely city with incredible history.
