Julius was very welcoming and keen to give tips about Berlin and the neighbourhood. He didn't stay with us, but his flatmates were really discreet so it actually felt we had the whole place to ourselves!

Description of the flat was accurate. The place was spotless and comfy, the room and the bathroom are large, lots of light.
We didn't really use the kitchen, but it had everything you could expect there.

Surroundings are nice and feel safe, there's a food supermarket right down the road, and plenty of bars and places to eat (most of them Turkish) in the area. Subway is 7m away or so, the Spree really close for a walk or a run. Bus stop to the airport is quite close too, it takes about 20 m to get there.

Only downside is the bar downstairs that played music late (on Saturday night only) , and you can hear a bit of traffic on Alt-Moabit road during the day, if you leave the windows open. But then it might be just me though as my gf wasn't bothered at all.

Overall it is a great place to stay, and for cheap at that, so we definitely recommend it to other travellers. We'd be happy to come back.
