The room is nice and cozy, the area is also very quiet. Everything is provided, even laundry detergent! The location is great, there is a 7-11 nearby and a 10-15 minute walk from the Asakusa station. If you're planning to visit Senso-ji, It's literally 2-5 minutes away!!
Manuals to remote controls and luggage-free travel services are provided in the room, in 4 different languages (if I remember correctly). So make sure to read them :)
The only (sort of) issue I have is that the stairs are quite narrow. I wouldn't suggest bringing a huge suitcase, but otherwise, this place is perfect.
