Location 5/5
Only 4 stops away from Alexanderplatz. Pretty central and easy to get to from either airport. Quiet street with good restaurants. A strange part of the location is that you're pretty much living in the host's pantry. We had to walk through their house and through a tiny door in order to get into our house. Also it's on the 5th floor with only a stair case so if you have trouble with stairs don't come here.
Cleanliness 4/5
Clean for the most part. It looked as if the floors hadn't been swept for a while, the tile in the kitchen was dirty, and the toilet wasn't the cleanest.
Amenities 1/5
The loft bed was hot and inconvenient (we were there in the summer). There was no flat sheet only fitted. The bedding (pillow covers, bedding, and fitted sheet) was scratchy. We asked multiple times for more toilet paper but we were never given any and we started with half a roll. The towels were itchy and small. If you're taller than 5'8" don't bother trying to take a shower. The wifi was also terrible. We could only get reception in a tiny corner of the house.
Responsiveness 0.5/5
Before we got there we had decent contact with the host but after we checked-in we never got any replies to our messages. I messaged the host at least once every day we were there about toilet paper and what we should do before we checked-out (cleaning, organizing, etc.) We know they were at the house because we heard them talking through the walls and pantry door. We still have not heard anything from the host and it has been about 4 hours since we left. We still have not received confirmation that they realized that we have checked-out.
Check-In 1/5
The person who checked us in was not the person in the pictures. I'm assuming it was the hostess's son... He only spoke German so if you don't speak the language have fun. He didn't really give us a tour of the place. No instructions on check out procedures or the unit. He was also unfriendly.
Overall 2/5
The only reason I would stay here again is for the location. Definitely not worth the money they charge, and I will be asking for some of the cost back. Amenities were subpar and not what you would expect from a 5 star Airbnb. If you've gotten this far and still decide to go my pro tip is to move the fan in the kitchen up to the bed and use it for circulation.
