Nice place, beautiful room typical Japanese style. Very clean, with a convenient 7/11 nearby.
The place is 40 min in total from Shinjuku and we had to walk 10min from the subway, which is okay.
As mentioned by Takeshi, the street can be noisy, however other guests might be noisy, make their laundry or dry their hair at night. Earplugs are not sufficient in this situation!
Takeshi has been very reactive to our questions!
