We stayed for one night at Tsuki no Yado Sara and had a wonderful time. The hotel is in a beautiful location overlooking the river and is only a short (5-minute) walk from the town. The restaurants in the area are quite expensive and busy, but there is a Lawson and 24-hour 7/11 nearby where you can pick up food.
We had a river view room so we could look over the river and mountains while using our private bath. The room was perfect, very large and equip with all the necessities and comfy beds.
There is also a public bath and two private baths available for hotel guests (no extra charge). There is a free drink bar with beer, wine, and spirits on the 3rd floor, as well as a free coffee and tea bar in the lobby.
The hotel staff were wonderful, very helpful and polite. We booked the traditional Japanese-style breakfast, which is ready at your table on arrival to your reservation. The food was delicious, with so many courses.
Overall, the stay was lovely and I would recommend it to anyone looking for a place to stay in Hakone. We would definitely come back!
