We thoroughly enjoyed our 1 night stay at the Alpen Hotel. The building/lobby is stunning and the staff were extremely lovely and welcoming. The room was amazing - quite large in size. We enjoyed the bath very much (not technically an onsen as it doesn't have spring water). The dinner was delicious (the chef was able to prepare a lovely vegan meal for us). We were still full when we arrived for breakfast! This is an amazing hotel in a stunning location.
