The hotel was really clean and the staff were super helpful and friendly. Toilet and shower facilities were shared and in excellent condition (the hotel provides body wash/shampoo/conditioner), fresh towels/toothbrush/sleepwear/slippers provided daily.
The sleep pods were fun! You have your own charger and light switch, and the rooms the pods were in were quiet and clean.
The locker spaces are easy to navigate, and my oversized baggage that didnt fit in the lockers were kept safe at reception with no issue at all.
The whole hotel has a no talking/quiet policy that means no matter what time you sleep, you aren't disturbed by noise (but if youre travelling in a group/pair, you might want to bear this in mind). If you plan on eating/relaxing, there is a table at the end of the bathroom available to sit at.
It's right next to Kanda station and made it so convenient to navigate - it's one stop away from the main Tokyo station and about 30-40 minutes from the Shibuya/Harajuku area. Akihibara was walkable from the hotel.
I found that the surrounding area felt pretty safe, but then I was only really exploring it on my way back from Kanda station. There was a starbucks a 3ish minute walk away, and a very useful 7-11 round the corner.
As a solo female traveller that doesnt speak much Japanese, this hotel was an absolute dream. While it would have been nice to have a social space/relaxation space, the location and price make this unbeatable for convenience.
