We stayed in Iori Hotel for one night and very much enjoyed our time. The staff is friendly and helpful, our room (Fuji) was compfortable and spacious enough for a family of 4, with views of nearby mountains. The interior decoration is rather minimalist with basic Ikea furnitire but it looks clean and organic and reminded us of some modern ryokans in Japan.
We did order a japanese dinner when we booked the place and though we didn't get any sushi, it was well ballanced and tasty, so if you don't feel like going anywhere or the weather is not good, it is certainly a good option.
The hotel is centrally located but maybe difficlut to find, so make sure you print the directions from the web site and update your GPS maps. Also note that parking maybe a challenge.
