The apartment is basically what the description says it is - nothing less or more. We liked the funky decoration and the accessibility (you walk literally right into it from the street)
We also liked the location since it was a 5 min walk to the subway and there were some "fast food" joints around the corner (apparently the best Vietnamese in town) and a small bakery.

Personally I was very pleased with the nice and straightforward communication as well as the way we could arrange the apartment hand over.
Anyhow, I'm pleased with the aparment pick during my Berlin trip.
