I very much enjoyed my stay in this apartment: the location was convenient for public transportation as well as a good restaurant scene, the apartment matched the posting, and everything functioned as expected. The balcony has an awesome view of the neighbor's incredible garden which was a huge plus, and you get very little street/outside noise: mostly all just the birds. The apartment is in an old building so the ceilings are high and it is spacious but the one downside to that is that the plumbing/drains don't function very well. The slow drain in the kitchen and the very ineffective flushing of the toilet were the two worst things by far but they didn't make a big difference overall because everything else was great. I had no issues with the wifi, the washing machine worked fine, I only had to restart the pilot light of the boiler once and it was no trouble, the bed was comfortable and there were plenty of clean linens and towels in good condition. I never tried the TV or the heat so I can't speak to them. I heard very little noise from neighbors: only occasional walking noises from above. The well-equipped kitchen needed some deep cleaning but everything else was clean enough on arrival. Would definitely recommend this nice apartment if you are looking for a place to stay in fancy West Berlin!
