Karuizawa Museum of History and Folklore

The staff was helpful from start to finish. The only complaint was that the mood light knob in the room was broken and have to take a day to repair. But it wasn't the only light available so just deducting one star. Got a 6000 yen credit for the restaurant from Expedia. Was a pleasant aurprise.

Loved the sauna and the large tub

This is a really nice room. I only stayed for a couple days but I would have been very comfortable here for an extended stay. The kitchen is very well equipped - you get a fridge, toaster, microwave, kettle, induction hob, pots, pans, rice cooker, cups (hot and cold), plates, bowls, utensils, even paper towels, and plastic wrap. The room also has an in-unit washer/dryer, and even a little vacuum. There's also a large table which was nice (many hotels, even aparthotels have tiny tables). The room I had included a bunk and a couch, and a "king" sized bed (which is two twin mattresses stuck together, but that wasn't a problem). The bed was firm but comfortable. The staff was also very friendly and helpful. The hotel is located in between Akihabara station and Asakusabashi station, so you'll be walking for a few minutes to get on the train. It's convenient to Senso-ji, Skytree, and Akihabara. There are also konbini's, a little grocery store, and plenty of restaurants nearby.
