We spent one night here in october, so it was a short experience, and hadn't tried all of the facilities, but this is a great hotel. Huge nice building in a great area, good parking, nice and comfortable room, great breakfast, good internet. The bed was really comfortable. Very clean, modern, well designed with useful furnitures. Supermarkt in front of the hotel, KLagenfurt is just minutes by car.
As it is located close to the canal which flows into Wörther see, and thay have private place beside it, this can be the best during the summer. Wörter see and the canal are just amazing.
