A free parking lot! No cleaning fee.
Generally, it's hard to find a large space where you can stay with your family in Japan. However, this apartment/condo is very suitable for a family of 2-6. Or, consider sharing with your friend to save money!
I'd be happy to help and support the guests if they need some information; however, I can't accept those who will not be able to communicate with me in either English or Japanese. Please understand that communication would be the most important to me.
