If you are considering Murren and Chalet Boebs, to borrow a saying--Just do it! Murren has a spectacular position, much closer to the Eiger, Monch, and Jungfrau than Grindelwald, and Chalet Boebs offers an excellent locale for viewing them. As other reviews have pointed out, the chalet is the last house in Murren on the way down to Gimmelwald. Rick Steves loves Gimmelwald, but we were very happy with Chalet Boebs'location, as Murren offers a range of stores and conveniences, while Gimmelwald offers a rural farm village atmosphere...and Chalet Boebs gets the best of both worlds. More importantly, while the chlaet offers no deck, its windows open on to a spectacular vista. Walks in the area are amazing as well.
Kitty and Albert are welcoming and helpful while respectful of guests' privacy. The chalet is well-furnished and comfortable. Both my husband and I really enjoyed the comfy bed and duvets, and I loved saving money cooking some meals with vittles from the town market, Coop. (Prices there are similar to Coops in other places, so no need to schlep food up to Murren to save money.) As others have pointed out, the restaurant prices are very high given a weak dollar, so we took advantage of the well-stocked kitchen and the pleasures of the spaciousness of our upper floor chalet apartment for meals. There is also a table outside when the weather allows for an outdoor meal at that altitude.
The locked room other reviews mention is indeed another bedroom (with bunkbeds--see the website photos) when more than a couple stay. I did a lot of research and comparison before choosing Chalet Boebs. While it is out of town and a bit of a hike, we could not have been happier with our choice of accommodation in Murren.
