We had a tremendous time staying at HJ's duplex! The views of the lake and the mountains from the kitchen and patio area were absolutely stupendous, and the space was more than adequate for our family of 3. HJ was extremely proactive, providing great instructions and helping us to locate additional dishwasher tablets when we needed them!
To note that while the place is walkable from the train station, it is a good 10 minute walk, so if you have a lot of luggage, call a taxi (we rented a car from mobility on the way back). Also the duplex is up a flight of stairs, and there are also stairs to navigate within, so it may not be for folks with mobility issues. Finally the upstairs bathroom is extremely small (the downstairs one however is large and well equipped), so if you have a large group this could be a consideration.
All in all, we really enjoyed our stay at HJ's place and we would love to come back!
