Robert's place was just what we needed. Check in was a breeze. He was easy to communicate with, and even picked us up from the train station, making a travel day with a toddler a little less tiring.
His place is modern, spacious, well stocked, and walkable to the Old Town and train station (5 minutes). The WiFi worked well. We cooked at home on most days, but enjoyed lunch at Villa Lido overlooking the lake and coffee at Como. Take a trip to the Benedictine Market. Incredible value for fresh, local produce and meats. If you have kids, make your way West to Europa Park. Great playgrounds and steps to the lake.
We picked Klagenfurt because it was halfway between Salzburg and our next destination: Venice. Although, I wouldn't hesitate to go out of your way to visit this town. It's adorable with it's lake and historic buildings, and it's a gem during the holidays. We would recommend Robert as your host in Klagenfurt!
