We had a nice stay at Kirsten's place. She provided us with good local tips and the apartment is really well located, just next to the Markthalle Neun, which is a fantastic place to eat and drink. Moreover she was always helpful and quick in responding. We just had two issues to be reported. First we couldn't access the internet and Kirsten had to come by and spend some time to fix it. It was a bit unexpected but things like this happens. Second it took some time for us to understand how the water supply is heated. As we were three, after the second bath, we ran out of hot water twice, and then had to wait some 10 or 15 minutes to have it back.
