We was charged with an extra amount for the check-in as we came 15min after the appointment due to traffic. The host charged 30€ on top of the 30€ - which isn't written in the rules. Also after the check-in we mentioned we don't got any hot water and the host refused any help and just stated it was apparently working before - at check-out she realized the waterboiler was broke.
The apartment is very central, but I wouldn't recommend it all in all. It wasn't cleaned properly and the furnishing was way more simple than pictured.
