Junko's place is a small apartment located in a very convenient spot. It is very neat and minimalistic. There are no elevators, so be mindful that you'll be going up and down 2 flights of stairs. All the amenities shown in the listing were provided. Although you'll find free Wi-Fi most places you go, the pocket Wi-Fi is more reliable and is a great inclusion of the listing (make sure to have a battery pack if you'll be out all day).
The apartment size is best for a max of 2 people if you plan on staying in often and want to move around freely. However, we were a group of 3 and managed just fine. It is only a slight inconvenience made easier by being tidy and moving things around.
Convenience is the selling point of Junko's place. Depending how fast you walk, it's a 5-7 minute walk to Tokyo Solamachi where you can easily spend the day shopping, eating and going up the Tokyo Skytree. Underneath, you'll find the subway (Oshiage station) which provides easy access to other areas such as Shibuya crossing, Harajuku, Akihabara and Tokyo city. There's also a direct line between Narita Airport and Oshiage station. Between Tokyo Solamachi and the apartment is a convenience store, a 24hr fast food restaurant (Matsuya), and a supermarket. The supermarket marks down food towards closing and you'll find fruit and vegatables 1 floor down. There's also a café just outside the apartment building.
All in all, the convenience makes for an easy stay.
