I have stayed at Ulli's place for about 1 month. The place is super clean and located nearby the center. I didn't have chance to meet Ulli during my stay personally, but it wasn't a problem at all. We communicated via email and Ulli's daughter came for the handover of keys. In addition, Ulli organized all necessary things remotely (e.g. a cleaning lady arrived several times during the time I was staying there). Guests could use the fully equipped kitchen - that was very nice as well. All in all the place is highly recommended.
