My husband and I stayed for 6 days in August 2008 at the Hotel Edelweiss in the breathtakingly beautiful mountainside village of Wengen. The hotel is a family-run concern and is efficiently and pleasantly managed.
The rooms are not luxurious but are extremely comfortable and clean and more than adequate as a base for exploring the area.
The continental breakfasts are simple but again, more than adequate. We were there on a bed and breakfast basis, but it is possible to arrange to have dinner if you inform the hosts early enough.
The view from our balcony was stunning, and the location of the hotel was a short walk up- or down-hill from the station. The Swiss rail system is, of course, super-efficient, and one never has to wait more than 10 minutes for a train.
We had the time of our lives on numerous cable cars - Schilthorn, The Faulhorn via First ((walked up through snow!) to name just two, and walked many throughly enjoyable and scenically spectacular kilometres up and down and around many mountains in the area.
There is a seemingly inexhaustible list of hikes of all levels which are accessible either directly from Wengen, or a couple of stations away, and we could have stayed another week and not run out of places to go. It did help that, with the exception of one rainy day, which we spent in Interlaken, the weather was great.
We took the train up to the Jungfrau - a very worthwhile experience - and would recommend an early start if one goes in high season, so that one beats the rush.
On a previous visit in 2005, I took the narrow gauge railway up to the Schynige Platte, and had hoped to go again this time, but didn't get there. Well worth the time and money.
We found Interlaken a little tired, and just another big town, so would not hurry to visit there again - but Wengen is another story - we'd love to go back.
