What I loved: location is very near Yoyoji Station (5mins walk) which basically means that you could reach almost every place of interest in Tokyo once you get the hang of traveling with the train lines. You can also go to the airport via this station while carrying a large luggage because Yoyogi has elevators that bring you and your luggage to the train platforms. This is an important insight especially if you don't really like walking for 15mins under the hot sun carrying your luggage to and fro Shinjuku Station. Meijie's place is clean and it has everything you need for your stay including a washing machine (she even provides laundry detergent for you to use) and some basic cooking utensils.
What I did not love: no elevator in the apartment building means you have to carry your luggage up and down the small staircases, that can be tricky especially if your luggage is heavy.
