Absolutely fantastic spot to use as a base for your Berlin explorations. I was there for business, girlfriend 'tagged along' to do some shopping. Everything is reachable on foot / rental bike / scooter / uber (ofc).
Berlin Hauptbahnhof is very close (10 minute walk).
The loft itself looks very nice and stylish with concrete and stylish furniture to match.
Everything was clean - there was a little fridge and a cooker for some basic in house cooking.
Communication with host was very swift and pleasant. Door opens with a locker system, so you don't need to rush to be there at a certain time to pick up your keys. I love that.
Will book again for sure on my next (business) trip.
