Our stay in Berlin was excellent. The apartment is very well located between metro and tram stations. It also became our favorite neighborhood in Berlin! Great restaurants, parks nearby, well stocked with grocery stores and bars around. The check in/out process was very smooth and they were very obliging though we arrived very late. The apartment is very clean (professionally cleaned) and we weren't disturbed by other guests noise. We cooked a lot in the kitchen and the bathroom was spacious. The room is nice but a bit small, there are larger rooms available for a little more money. Overall really nice time, they seem to be pretty experienced hosts.
