Very clean and good location in Neükolln. Checkin was very easy and Alex was quick to answer any communication. There was some noise from the street and from within the building so I could only sleep with earplugs, but I'm a light sleeper. The bed was quite hard and made for one although I was alone so it was not an issue. There is an emergency light in the hall which doesn't turn off and is bright at night, but i could shut the bedroom door to block it out. The lights and fans in the hall and toilet were on timers so they couldn't be turned off and on, which I found annoying sometimes. The shower is separate and in the kitchen. The furnishings were nice, like a hotel. The flat was very clean and was fine for my 3 night stay. The elevator in the building and keyless entry were great.
