We arrived late at night to the apartment, around 01:30 am,
The house manager greeted us, she doesn't speak much English, but that's fine, everything is sorted out inside the apartment , the wifi password, we were even greeted with some german champagne and beers, apartment was super clean, bigger then it looks in pictures, was comfortable for three people and I can calmly recommend for 4 as well. Monique and Chris were active and informative so was easy to chat with.
Overall location is great 10 ~ minute walk from Alexanderplatz.
I recommend it from the bottom of my heart:)
