Gris’s place is in a central location with a lot of food choice, grocery stores, pharmacies... Very convenient for JR pass holders since the nearby train station is on yamanote line. Also convenient if you use Tokyo metro subways. Cons: it’s on 2nd floor with no elevator so not recommend for elderly people or if you have a lot of big suitcases. Gris is very quick to communicate if you have any problem during your stay. He also allowed us to drop off our luggages before the check in time.
