Washer/dryer took a much longer time to dry than Australian dryer-only, causing us concern about over-heating/damaging our clothes and/or fire hazard. No kitchen sink plug.

Great reception staff , always with a smile willing to help ! We stayed one week in family suite (2 bedrooms + 2 bathrooms) , this kind of room is a perfect choice for a family of 4. Rooms were clean and well maintained , there is a daily cleaning + one time bedding changing. The location is in quite area , but in short distance of grey / red lines, so you can easily reach every point in Tokyo + Haneda / Narita airports by using the red line (Askusa line) Many restaurants are near by and familymart just in 2 min walk. The luggage transfer service is available (look for promotions) and very convenient.

Still thinking about it :) nothing so far

Having a two bedroom and two bathroom room was very nice for a group of four. It’s very spacious compared to staying in standard business hotels. Having a washer and dryer is also very convenient. It’s located just a few minutes walk from Ningyocho Station and is also right next to a FamilyMart, so access to things is pretty good. The neighborhood has a more local feel and has plenty of good food within walking distance.

Only thing we didn’t really like was the shampoo and body wash that was supplied, but that wasn’t a huge issue since we brought our own.

The hotel's location is excellent: 100 metres from a metro station entrance, a family mart just downstairs, and many good small restaurants at your doorstep. I cannot expect a more convenient hotel location than this one. Our room plan is a two-bedroom family suite. My two teenagers use the bunk bed, and they cannot be happier. There are two full bathrooms in the suite. Our master suite has an ensuite, and it's very convenient.

Nothing at all! The hotel is perfect! But it would be great if there were one even bigger suite (like three-bedroom suites).

We had a very spacious two bedroom, two bathroom apartment which was fabulous for our family of four. Additionally it had all washer and dryer in the apartment itself. The property is located in a quiet residential area of Nihombashi and this was the best thing about it, you do feel like you are getting away from the hustle and bustle of Tokyo whilst not actually being all that far away from the action. Beds are super comfy and staff were lovely. There is a Family Mart next door and a supermarket nearby where you can get supplies, and it is a 5 min walk to Ningyocho station. A great place to stay for families.

I love everything about this hotel. There's really good coffee at the 2nd floor. Ningyocho station is within 200m (this connects to Asakusa & Hibiya Line). very easy to go to tourist places like Ginza, Asakusa and even Disneysea. Family mart is within 30m of the hotel. very convenient to buy food which can be reheated inside the room. Hotel staff are very accomodating and friendly. They speak good english too. The room is quite big for Japan standards. This is more like a serviced apartment than a regular hotel. But with the convenience of a regular hotel (changing daily towels and cleaning of trash). I love how my kids were able to borrow picture frames and other items from the reception to decorate and personalize our room. Plus points for washer and dryer inside the room too. I will definitely come back to Mimaru Nihonbashi

None. This hotel is perfect

The location is perfect; the hotel is only a few minutes walk from the subway and there are plentiful restaurants all within a 10ish minute walk. The staff spoke English fluently and were very kind and helpful with any inquiries we have. It was also very nice to have an in-unit washing/drying machine to toss our dirty clothes into every night.

The bed was firmer and the pillows were flatter than what my group is usually used to from back in the US, but we got used to it fairly quickly.

Very nice and clean place, all essentials were there - bathroom supplies, towels, and kitchen supplies with utensils. Additional washer/dryer was very hekoful. They provided a Toaster oven on request.

Nothing

The apartment was very beautiful and extremely comfortable. A real luxury for a family of five, with three tweens. It was comforting to have somewhere private to decompress at the end of each busy day: with a Family Mart next door and a place to have some quiet tea at home. The apartment exceeded my expectations and I especially loved the bathrooms and window-screens. The area is quiet, dignified and respectable. I felt very comfortable walking around at night with my children. It was easy to get around and find lovely places to eat nearby.

It was very expensive.

We stayed for 10 nights. Great location just 2 blocks from Ningyocho station which allowed us to get anywhere in Tokyo quickly. This station is on the Asukasa line which takes you straight to Narita. Many great eating options within a short walk. Grocery and convenience stores very close as well. Family Mart on the same block so we would send the kids with their IC cards to buy drinks and snacks on their own since Japan is so safe. Staff were so nice and courteous. We had a family suite which was perfect for our family of 4 but if we had another 1-2 kids it would have been fine.

Not much to say here - I liked it so much I am already planning the next trip!
