My pre-requisite for booking any Interlaken hotel for our stay was a minimum 4 star, sauna and a double bed. I love saunas and for me after my daily exercise program a hot sauna is perfect to relax! Your reception staff were excellent on arrival. When I enquired about the sauna, she explained that as long as I notify reception, I can request a sauna at any time. On day one I had a fabulous 86-degree sauna at 7.30am, it was great to have a “proper” heater and not the infra-red heater that are so common nowadays and to relax afterwards in your solarium area. The only comment was the glass door is a real struggle to close and requires attention. On day 2, at around 5.30pm I went to reception to request a 6.30 am sauna the following morning, the male receptionist was attending to a customer. Whilst I was happy to wait , one of his colleagues , the porter asked if he could help me. I explained that I wished to have a sauna the following morning at 6.30 .. He said he would ensure a message was left for the sauna to be ready for me. At 6.30 the following morning I proceeded to the sauna and wellness area to find a cold sauna. The ”double bed” in 101 is shocking- It is 2 single beds pushed together with a double sheet over the top of the two singles. There was a huge depression between the two beds . The bed looks like a roller coaster ! So much for a double bed to snuggle up to my wife in bed ☹ Breakfast overall was very good. The selection is amazing , the fresh fruit, fresh fruit juice, and much more ..it did have the wow factor however the bacon and sausage were sat in a pool of fat or oil. (Many of the better hotels tend to put a few slices of bread under the bacon and sausage to soak the excess fat or oil up.) 10/10 for the fabulous Christmas decorations ! I do make a point of reviewing any place that delivers exceptional customer service as much as those that disappoint.
