友政's place was in a great location, because it's only 5 minutes from Koenji Station, which makes it eaay to travel around Tokyo. It's also a JR Station for those looking to use their Japan Rail Pass.
It had all the amenities you need if you're using it as a base of operations so that was good.
As others have said it is on the small side (the bed takes up about 3/4 of the room) so if you are planning on bringing 2 large suitcases it would be a real squeeze.
友政 was an excellent host. Clear communication from start to finish. Quick to answer queries too (particularly when we first arrived late at night). 友政 also made sure we were aware of reduced rapid trains at the weekend which really helped with planning our departure.
I would definitely stay again, but think it's better suited to one person.
