Eden 2 was large, modern and comfortable for my family of 5 adults.
By far its best features are its large outdoor deck (maybe 50 sq meters, with great mountain views) and its location, close to town and train/gondola access.
We visited all the popular towns of the Jungfrau region-Grindelwald, Lauterbrunnen, Murren, Interlaken, Thun and others. Wengen has the best combination of desirables - convenient access to hiking through trains/gondolas, pedestrian-friendly with no car traffic/buses, small town charm and great views.
We'd love to come back for another stay!
