I have to say this is one of our favorite hotels in Tokyo. Really interesting and beautiful. Rooms with amazing designs, and conveniently located in a not-busy area of Akihabara.
We travelled with our 6 year old son and he loved the room we got (athletic room). We also walked easily to the nearest station for both JR and metro, both about 10 min walk.
We appreciated the washing-dryer machine in the room, but it would be great to have a little instruction manual in English, because it took us ages to translate it.
We had good nights sleep during our three day stay, and will definitely go back to stay in this hotel.
Great job to the amazing artist, designers, and the kind staff.
Check-in was a breeze, done on a tablet. Very fast.
We left our luggage in the morning of our first day, and everything was perfect.
