We stayed at Hermanns apartment for 3 nights and could not be happier. The location is great within easy walking distance to the city centre, but also some very nice restaurants within a few blocks. There are two supermarkets vey close by as well. Public transportation is just around the corner and made the transfer from/to the airport very easy and quick.
The apartment was clean and tidy and just as shown on the photos. The bed is big and comfortable.
We stayed when it was very hot outside and wanted to keep the windows open during the night, but had to close them due to traffic noise. Once closed it was not a problem for us at all, but if you are noise sensitive, this may not be your choice.
Communication with Hermann was swift and he was very flexible with our check out time, as our flight didn't leave until the afternoon and it made a hugh difference for us.
