We (me, myboyfriend and another friend) spent two nights at Ernst's place. The house is very beautiful, clean, comfortable and very well connected to the subway and the city centre. Ernst is very welcoming. He and his wife were not there during our stay, yet the check in and check out were very well organised and Ernst contacted us by phone and messages before our arrival and during our stay, to make sure that we felt comfortable. I can definetely recommend both Ernst and the location.
