It's a quick stroll to Keikyu-Kamata station which easily connects to Yokohama, Shinagawa, or Keikyu-Kawasaki (and more).
It's quite close to Tokyu Plaza, which is this huge shopping strip with lots of fantastic restaurants and shops, like a Donki (Japanese version of a Walmart).
The place itself has everything you need, and all the amenities are there for a month or longer stay. (Plenty of toilet paper, tissues, shampoo, body wash)
On top of that, it's very clean.
Anyways, I feel like I can't overstate how great this place is. You'll just have to stay here to really get this amazing experience.
If I wasn't already moving to Osaka, I would definitely stay here longer.
