The flat is nice, location is perfect. Christian is very helpful and replies immediately if any question occurs. The only misunderstanding turned out regarding the time of checking in / out. It is written that between 9-19 any time is OK, but not written that one has to define it before the actual booking. Must be fixed well before when one wants to arrive and leave. So I did disturb the previous couple who were nice to leave earlier to give me the flat in time. I also wanted to stay up to 4 pm, but finally was requested to leave at 10 am. My suggestion is that check in /out time must be given more precisely. Otherwise my stay was very pleasant and thanks for providing this nice comfortable place to stay and thanks to Christan, his friend and mother.
