The room is exactly as advertised and has everything you could want/need for a great stay in Tokyo.
The room was clean, and things like free towels/shampoo/body wash etc were highly appreciated (as was having a washing machine in the room!)
The location is brilliant, super close to Akihabara (probably less than 10 minutes walk), and close to the train station which is very convenient. There are also plenty of convenience stores nearby, as well as a supermarket, and even several pizza places if you don't feel like cooking after a long day.
Check-in and check-out were both very easy, and the details of everything were well written and explained by the host prior to arrival. Na is also very quick to respond to messages, and always happy to help if needed.
I can't recommend this place enough, if you are travelling alone (or as a couple/pair) this room is perfect.
