The apartment is in a very good condition, looking modern and has an overall nice and calm feel due to the minimal and tasteful interior design choices. The location is excellent (a bit noisy only on the weekend yet close to come back from a night out) as it is a side street having 2 metro stations nearby.
Due to the big window the place is still light even on a cloudy day, no noise from neighbouring apartments and the bed is comfortable (was a little skeptical at first as its not a "classical" one).
Downsides - don't really see any, except if You're into taking loooong showers You better keep it more minimal (plumbing is not very efficient).
