Great location, great host, comfy room with a large bed. Just 3 tram stops from the main station Alexanderplatz too :) . Host was nice to chat with and she gave me personal recommendations on winter markets, chocolate shops and some restaurants. Super appreciate it. Coffee is provided and is super good too! I love all the little touches of decoration and the big effort to remain environmentally conscious throughout the household.
Would highly recommend that you stick to the check-in times. Self-check-in is a bit of a hassle especially if you're carrying alot of heavy luggage, as the key is located in a different building across the street.
