We didn't meet Boris in person, because he was out of town, but the communication was great and easy-going. The place is clean and sunny with a nice terrace.Great location in vivid Kreutzberg streets, near the U-Bahn and bus stations, but really quiet for resting after long-days wandering around the city. A spare bed sheets would be useful and maybe some brighter light for the late-evening map searching. Besides that little things, everything was great for us, so we would definitely recommend this place and Boris. Thanks for hosting us and take care!
