Nice place within walking distance of Yotsuya-sanchome station (JR Shinjuku station is a few stops away on the Marunouchi line; Tokyo station is accessible as well from the same line). Convenience stores, restaurants, supermarket, coin-operated laundry are also nearby. Shinjuku Gyoen Park is nearby as well. The place is small as most apartments in Japan are but it was sufficient for my family. Hiro-san provided some Japanese snacks which were a welcome treat. He responded to all my queries in a timely manner, suggesting restaurants to try and some tips to make our stay better. I left behind some items and he was able to ship them to me at once. I would recommend this place for families looking to have Shinjuku as their base when they tour Tokyo and the surrounding areas.
