Great place to stay in Tokyo.
The room is clean and spacious. Because it's on first floor, the window doesn't allow a lot of sun in the room, but you can choose the intensity and the color of the light and it's enough to make the room quite enjoyable.
The facilities are clean. Plus room C is at the end of the corridor so you won't really hear sound of the showers.
Be aware that there is a shared fridge and a boiler, but no proper kitchen and almost no dishes. It can be a low point if you are travelling with a low budget.
Location is great, you can walk to Ueno in 20min, but there is Iriya station at only 8min walk if you prefer to catch a metro.
There is some convenience shop near by.
The place is mostly quiet. The walls are fin so the quietness of the place depends on the level of respect of the other guests.
I only saw once the man who is cleaning the place and he was very nice and friendly.
Overall it was a nice stay in a convenient location.
Just a real kitchen would have been mostly appreciated for the price.
