This hostel seemed convenient for a few days around NYE together with my partner in this popular neighborhood. Anne communicated remotely, but was always responsive and our check-in went smoothly.
We booked a double room which was adequately comfortable; spacious and the bed satisfactory for a good night's sleep. The walls are paper thin however, so for privacy reasons alone I would probably reconsider if you're a couple.
The hostel is clean and tastefully designed with some complimentary provisions. It did have some visible maintenance issues, and my largest gripe was that the water pressure was very low in both shower cabins downstairs.
The location is a perfect base, with all our chosen hotspots easily accessible and we very much enjoyed conversing with some of the younger residents during the new year celebrations.
If the showers are fixed and if you don't put too much emphasis on privacy, this could be a good choice in Kreuzberg. We enjoyed our stay overall, thank you Anne
