We stayed here for a month. The flat is in a superb location, both for transport, supermarkets, and for going out to bars and restaurants. Treptower Park is a short walk away, which is a great place to go running, or to hang out by the river.
It is very well equipped, and the kitchen amenities are especially good. It is also nicely decorated throughout.
Check-in/check-out and general communication with David was easy.
Some previous reviews noted the noise outside. We did not have this problem. There were two of us, and we were not disturbed at all when we slept in the main bedroom. It is possible that if someone slept in the lounge area, instead of the bedroom, and wanted an early night, the people in the bar outside would be disruptive if the windows were open. However, there was no drilling in the building or outside the flat for the duration of our stay.
In short, it’s a great flat, and we would love to stay here again in the future.
