Very close to JuJo station which is especially good for JR Pass holders, as Jujo is on a line that is free to use for JR Jass holders.
The place is very small for 4 people, it's not a comfortable space whatsoever for 4 so would only recommend as a last option. The shower is also a complicated 9 step process to turn on that must be done every morning.
It's an okay enough place, it's just not very nice to be in for anything less than sleeping because of it's size. Even for Tokyo.
