Malte was there to let us in at 10pm as arranged. He gave us details of nearby restaurants etc. and was helpful when I needed to find a launderette - although in fact I ended up using the washing machine there. The flat was fine - a little scruffy around the edges and the kitchen a little worn but weren't doing a lot of cooking so that was fine. A toaster and a couple of mugs would have been nice. The area is well-connected but a bit dead around the flat - to get to the food and nightlife of Kreuzberg proper you need to go a couple of U-Bahn stops but it was very near a stop - Prinzenstrasse. The WiFi connection was good and the heating also good. The neighbours were a bit noisy - stomping around above us but nothing too awful. All in all good value for the price and location.
