The apartment looks like the pictures, is located in a nice neighbourhood and has everything you need for a short stay in Berlin (equipped shared kitchen, two shared bathrooms with shower, toilet and hair dryer, your own towels and a small privat bedroom). To the public transport station you walk around 10 minutes. There is a Rewe and Bio supermarket around the corner.
Check in was really easy. Cleaning was every day or every second day for the shared areas. Since you share the apartment with +/-9 other people it can still get kinda dirty.
All in all it was good, but really expensive for a shared semi clean apartment. (51€/night)
