The appartment is very well located and very clean. But the windows do not open properly so that you can't get any fresh air at all. We planned to stay in the appartment for two nights but we couldn't stay both nights because we couldn't get any good sleep. The road directly next to the appartment (the appartment is on the ground floor with the only window towards the busy road) is very busy all day and all night. So we left the appartment one night earlier than planned because we couldn't sleep restful at all. Basic things like a knife for cutting was missing. There were no coffee pads for the coffee machine as well so we needed to buy coffee pads that only come in a big package. This could have been easier if Christian provided some coffee pads.
Beside the location and the cleanness we wouldn't recommend staying there.
