We (2 adults and 3 big children) were at Klaus's place for 5 nights.
The apartment is huge and very nice. Klaus is a very good host, he helped us with all our needs, for example he found for us a laptop adapter. There are big bathrooms and big kitchen. There are washing machines, and dishwashers but you need to bring with you soaps for both of them. The apartment has a big balcony with place for children to play.
The top of our stay at Klaus's apartment were the Jacuzzi and Sauna. The location of the apartment is convenient. It's close to a supermarket and just ten minutes of driving to very lovely Molveno lake.
We highly recommend Klaus's apartment.
