Location: Just neat 京成立石 Station, it is a good place for visiting east area of tokyo(淺草、晴空塔、上野、築地), and it's easy to find just follow the instruction from the host.
Facility: Host provides everything you need, no problem
Others: It's spacious even for 8 ppl, two toilets is great but only one bathroom is the only shortcoming.
Host was so nice that providing us three bottles of Japanese apple juice, it was really warm to us.
