We stayed at Masahiro's Jemsty Inn for two nights during Golden Week. Overall, we were very satisfied with our stay - Masahiro has put together a really nice inn experience. The inn is only a ten minute walk from Izu-Kogen, and you pass by one of the main "tourist" strips of the area where there are cafes and the Teddy Bear museum.
Masahiro was really friendly when we met him, as was his front desk staff. We were given slippers and yukata (Japanese robes) upon check-in, and were given a tour of the establishment. It made me think of lodges I've stayed in in the States - older layout, but comfortable. Our room was clean, with wonderful thick comforters on Western style beds. While some of the decor and utilities were dated (think pistachio colored sinks), they all functioned just fine.
We were offered a breakfast option for 500 yen/person, which we took (rice, salmon, miso, etc.). There were also dinner and karaoke options, which we did not take.
Minor cons, which I ultimately did not factor into my review:
- There are only two showers, and these are connected to the (excellent) onsen/hot springs. There are eleven rooms in the building. We had to wait to use the showers, though in the morning the wait was not that long.
- The walls are a little thin. The room next to ours had a party, and the noise levels were a little high.
- All combinis/groceries are on the other side of the train station and in the town itself, so be advised if you want snacks.
Overall, I highly recommend the Masahiro's Jemsty Inn. It's near the ocean, near the mountains, rural lodge in feel but close to civilization. I had a great time and I plan on going back!
