I love Kimmy and Dee's places! I stayed in both apartments while I was in Tokyo, and they were very clean, comfortable, and convenient. The alleys between the apartments and Asagaya Station are full of some of my favorite bars and restaurants in all of Tokyo. Highly recommended if you're looking for a non-touristy Tokyo experience. As for the place itself: Good heat system, good bathrooms, good beds, and closet space. Super-easy checkin. Kimmy and Dee are very communicative if you need anything, and their house manual is super-detailed.
