We had a great time staying at the Loft in District 7 - Neubau. The room was very nice and clean, the bed slept good, clean shower, there's a TV with AppleTV to play your own media, youtube or wathever.
For us it wasn't a problem, but the (clean) toilet is right outside, next to the entrance of the room, with a key to lock & unlock it.
The location is super, everything within walking distance to bars & restaurants, shops, musea, city center, parks, public transport etc.
Niklas is a good host, he even gave us an Easter present.
Thanks!
Sebastian & Eyleen
