The location is very nice and directly in the Center. The Apartment is very small and quite clean but could be better. The shower is leaking a bit. Otherwise it is well equipped. What made me give the bad rating is the communication. They are sending one standard text to you and then not answering back if you have any concerns. I forgot my bracelet which they send a picture of to me and now they are not replying to my texts! Communication is almost not possible with this hosts.
I hope Martin and Klaudie are changing this immediately otherwise I would not recommend taking this apartment.
