The apartment was lovely, very clean and nicely decorated. Lots of flash touches like fancy dimmer switches, and all the equipment you'd need. The hosts also left some little treats which was cool.
The location was also great, only a couple of minutes from the Ubahn and a good supermarket.
Check-in and out was smooth. The keypad system works really well.
Only downside was that there was a little bit of noise on a couple of the mornings (drilling and banging). Not sure what that was, but not too serious, and presumably only a temporary thing.
