Nice room overlooking the lake. The room was very comfortable and sound proof. On each floor, as you got off the elevator, there was water and fresh fruit for the taking. The buffet breakfast was very good, with the best croissants I've had in years and wonderful fruit salad, breads and jam. The shower was a walk in with the half door as is the case in most of Europe. The floor was extremely slippery and we both almost fell more than once, even though we were very careful. Also, since there is no door on the bathroom, anyone taking a shower is in full view to someone coming in the door from the hallway. Also, no bars to hold onto in the shower. The beds were very comfortable, no air conditioning, but they did give us a fan. I was told A/C is not allowed...who knows.
Front desk staff very helpful and pleasant.
No peephole in the door, that would be nice.
Overall, a nice hotel.

Stunning hotel spa in central Switzerland on the shores of the Lake of Thun.
Newly reopened after extensive renovation and expansion. Newly built 2 story hotel overlooking the lake. Extensive remodel of 2 older mid 1960's lakeside buildings that now house the hotels spa. Indoor and outdoor pools, saunas, steam rooms, massage rooms all located in the spa. Onsite spa staff available for wide range of spa treatments.
Checkin was quick and seamless. Lakeside room was spacious and modern. Large washroom with very large glass enclosed shower and separate WC. Bed very comfortable with large soft hypoallergenic duvet. Large flat screened TV. In room electronic safe. Ample closet space. Luxurious bathrobe and slippers provided along with extra towels for use at the pools and spa. The hotel was very quiet for sleeping. No noise from adjoining rooms or hallways even though hotel was full overnight.
Hotel has large restaurant overlooking the lake. Seating has both intimate tables for 2 and larger tables for 4, 6 or more.
The dinner menu and wine list extensive. Dinner came hot and cooked to perfection. Wait staff was very attentive.
Breakfast had many choices. Fresh fruit, yogurt, muesli, cereals, fresh baked bread and croissants, cheese and sliced meats. Hot eggs, strip bacon, hash brown potatoes, sausage. Choices of fresh fruit juice, teas and coffee.
Checkout was as easy as checkin.
Ample reduced rate parking for hotel guests and public bus stops outside the hotel entrance.
I would definitely stay longer on my next trip.

We spent 4 days at the Deltapark and we were all impressed. The front part of the hotel is brand new. The decor and rooms are beautiful. Some colleagues stayed in the original triangular buildings. Apparently these rooms have not been updated but they said the rooms were fine. Our only complaint was that there was no A/C and some nights got quite warm. The food was quite good and the bar near the lobby was well stocked. The meeting rooms were well equipped with the latest A/V equipment. I heard plenty of positive comments from everyone. I would recommend the Deltapark to anyone if they are in the Thun area.
