Communication with Philipp was very good at all times. We had a big delay on our trip and he arranged everything so his father Christian could check us in at 10pm - we did appreciate that. However, when he was showing us the apartment he made a very sexist comment by saying it wasn't necessary to explain anything kitchen related as 'we were women and that was our territory'. Shocking.
Also, towels were lacking, they were old and smelt of humidity, and there were no basics as gel or shampoo. But the apartment was big, clean and very well located.
