Minn Nihonbashi is in a quiet family-centered neighborhood. It was a fantastic location for our family to recuperate in the evening after busy days exploring Tokyo. There was a grocery store next door, and a Family Mart just two blocks away. The hotel is about a 5-minute walk to two subway stations: Ningyocho (Hibiya and Asaksusa lines) and Bakurocho (JR Sobu line).
The unit was clean, quiet, and comfortable, with a deep Japanese tub and a combo washer-dryer (detergent provided). The small kitchen was minimal, but had everything we needed for our six-day stay: two burners, fridge, microwave, tea kettle, rice cooker, *toaster oven (yay!), two pots, skillet, paring knife, chopping knife, cutting board, sieve, two mixing bowls, plates, bowls, cups and utensils. It was the best appointed kitchenette we had during our 14 days in Japan, and we used it every morning for breakfast, and every evening for dinner.
One thing to note is that this is a bit of a self-service hotel. The desk is minimally staffed, and you check in using a QR code. Fortunately someone was at the desk when we arrived because our jet-lagged brains had a bit of trouble figuring out what we needed to do (they have a QR code you can scan at the front desk for temporary internet access during check - helpful if you don't have international roaming turned on yet). Since the desk isn't staffed, the hotel does not send or receive luggage, but you can forward luggage from Tokyo Station (so worth it!).
The room was reasonably clean. We did had to clean the top of the bunk.
Didn't see any staff actually onsite but we were able to contact them via the video com when we needed to speak to them.
Love the fact that there was a washing machine and a dryer combined (dryer actually dry). As the toilet didn't have a drying function (like with some Japanese hotels) it took over 12 hours to dry - can't complain as not many hotel rooms have a washer and dryer.
Kitchen - has a fridge/freezer, microwave, 2 hobs, kettle, a grill/toaster, cups, plates, bowls, cutlery. Table and chairs for 4
The room was very spacious.
Great and convenient place to stay. Close to train station, 7-11 and family marts. Easy to get around. Grocery store near by. Awesome place! Room was spacious for my family of 4. Clean, great amenities.
