This is very good value for a tokyo stay , clean , good location ... like almost all Tokyo addresses , not easy to find, but be patient . It is a bit easier if you have a little japanese, but that isnt a barrier. Try and have the address in japanese with you , so you can show it to locals , or the piceman on duty in the police box nearby . It is on the Oedo subway line, so you have to change off the JR line ( Yamanotesen). A strong recommendation is to change trains at JR Yoyogi station , not Shinjuku which is enormous and complex until you get used to it . Strong recommendation on property, clean , works , family have stayed more than once. Go for it . Cob
