Akihabara Nakagawa Inn

This was the most affordable place I've been able to find that can accommodate 4 large people in one room with tatami mats. It has it's own bathroom, closet space, and necessary amenities. The hotel was within walking distance to Okachimachi station and Akihabara so it's a bit of a hidden gem. It has a genkan at the entrance so it feels like a studio size apartment. One thing to get used to is sleeping on the futon on the floor, but it is thick enough to sleep normally. The staff can speak English really well so it'll be easy to get assistance. It's located next to a lot of restaurants so there's always something different to eat. There's also plenty of artisan stores to buy unique fashionable clothing and accessories. This is one hotel I'd recommend for a small group. The rooms are actually bigger than the picture show so there'll be plenty of room for a family.
