The biggest issue I had was with space. The room is small in general but the bathroom is especially small. Basically it is a tiny room with a faucet and a toilet that doubles as a shower room. There is only a bit of room to keep your towel and paper towel dry if you intend to keep them there while taking a shower. After the shower, if you want to use the toilet, you need to wipe it first, then either wipe the floor or take your pants off completely. I was not expecting this. If I were to reconsider choosing this place, it would be because of the small bathroom.
Otherwise, this place is only one station away from Shinjuku and will make your trip back home very easy. There are many restaurants nearby, even the ones that run 24/7, as well as places to buy stuff last minute. The room is alright and checks all the boxes in terms of amenities.
