The place was well situated close to U+S Bahn stations as well as tram lines, and is within walking distance of key attractions and in the vicinity of some great food and drinks options. The place was clean and stylish, with everything you need for a short stay in Berlin.
There were three of us staying in the apartment and as a single large room (studio) it would be uncomfortable to have more than that in the room given its layout (although the room itself is well sized), and with the beds in the room there is little area to sit comfortably, which was disappointing for the price.
However, overall it was a comfortable stay in a good location, and would recommend to couples but not ideal configuration for groups of more than that.
