The location is a bit out of the way. Kosagoe station isn't on the limited express stops for the Tobu line so you have to make a transfer from Shimo-imaichi station on the local. There was never an attendant on duty and there is no ticket Kiosk at this station, so we ended up paying fair adjustments at our destination stations. Nikko is about 40 minutes away by Tobu.
It's about a 10 minute walk to the hotel from the station. It's straight down the road along the tracks, but pull up a google street view before you go, that helped.
We got tired of making that walk and had the front desk call a taxi for our luggage when leaving.
There was really no english spoken at all from the staff, but it didn't cause any issues.
None of these were really deal breakers, though. We were happy with everything else.
It's a very relaxing experience. The room was clean and comfortable. The beds were a little stiff, but big. Also, the linens were quite comfy.
We spent 2 nights in October 2014 and the weather was just cold enough to enjoy the hotspring water properly. The personal hotspring tub is super nice, can fit 2 regularly sized people. Also, the pool, hotspring, and Jacuzzi area is really nice. The gym is decently stacked with nice machines, but the 'game corner' is kind of an after-thought.
There isn't a lot in town we could find for food, so the half board is worth the money, it's all-you-can eat and the food is pretty good. Dinner was a mix of 5 or so entrees not including rice, noodles, and other sides. Breakfast was scrambled eggs, sausage, ham, a few Japanese menu items, and sides. All and all it was pleasant.
No English spoken really at all, but able to communicate pretty effectively without. They did have some literature in English.
Really relaxing environment and we were really able to unwind after the first part of our trip in Tokyo.
The first day we arrived started with us checking in, followed by drawing a hotspring bath on our private balcony, followed by a nap, a buffet dinner, a 15 minute session in their lobby massage chair, ending in a rooftop Jacuzzi soak. Very soothing.
I cannot speak to the quality of the onsen because with all the private amenities we never got around to booking the private one.
We were right about the parking lot, but still a good view in my opinion. Also... baboons! This was probably not normal, but the first day my wife spotted a family of baboons around the parking lot and we got lots of great pictures of them playing around.
All and all we felt it was worth the money.
