Perfect place in Shinjuku. 17mins walk from the main shinjuku area (using Hotel Gracery). If you take a taxi from Hotel Gracery to the house, it will only cost you 1,000-1,400 yen.
But really near the JY line Shin-Okubo Station (Yamanote line) and JB line Okubo Station (Chuo Sobu line). That’s your main stations if you will stay in this house.
For food, you can walk to IWA Yakiniku Restaurant that is really good and a breakfast place called TRIANON CAFE. They have the best egg sandwich. There’s also TATSUNOYA if you like ramen.
The Midori place is so huge that could fit a family of 6. It’s like you are staying in your house because it has enough space to walk around. My only concern would be a single shower and toilet (although they have different doors) only 1 can shower at a time.
Everything is PERFECT! Midori is the BEST HOST! She will make sure everything is ok and that you are comfortable. We stayed there for 10nights and is really good for senior citizens like my mom.
