We got to a nice apartment in a nice place. Unfortunately,there was a problem with the hot water in the shower. We were asked to wait another day for the company to come and check the shower - which is really unexceptable. We asked Mara to check us out after one night, found a different apartment in Berlin where we stayed for three more nights. To our surprise, Mara refused to check us out when we left, and insisted on charging for the whole four nights we ordered. Thanks to Airbnb we got our money back. This is not a way to treat guests!
