I went to Japan with my big family consist of 12 adults and 1 kid and we stayed in these 3 Hiro’s apartment. All is considerably very good. The neighborhood, metro and bus station and also the location itself is very good. However, it is quiet small for staying 4 people in a room of each apartment, esp. when we packed or opened out suitcases. I suggest not to bring big suitcases if you stay in this apartment.
Overall, it is a very nice experience. THANK YOU HIRO!
