To start with, the chalet swiss is a good hotel. its 3 star like facilites and structure and facilities are quite good. The room was not great - it was great in size and view ( snow covered peaks ! ! !) but it lacked good furnishings. The bed was okay but all the time you were living under the fear of the person staying on the floor above you breaking into your room as a result of the ceiling being very shaky. The sound of the foot steps on the floor above were a real nuisance and i pity the people living below our room. The tv was ridiculously small. The breakfast was good. Location was okay though thats not a problem as interlaken is very small.
f you are getting a decent price- i would say go for it!! we booked late and paid a high price.
