Naomi goes above and beyond as a host. She gave plenty of local tips, and was very quick to answer any questions that I had. Her guidebook is fantastic. It describes in detail how to get to the apartment, everything inside the apartment, and the surrounding areas.
We travelled as a family of 5. 3 adults and 2 children (ages 4 and 2). Everyone was comfortable in the space. The toilet is in a separate room from the shower, which is convenient. The floor mattresses were more comfortable than I could have imagined.
The location of the apartment is great. It’s pretty much in Korea Town in Shinjuku. The nearest green line station is less than a 10 minute walk. They are tons of restaurants and grocery stores right at your doorstep.
