I would strongly recommend Kotaro’s place! The location is amazing! It’s right in the middle of some of coolest neighborhoods in Tokyo: Ebisu, Daikanyama and Meguro. The bars, restaurants and cool vintage shops are in walking distance from the apartment.
Kotaro is an excellent host: checking in and out is very easy, the tips he provides are great and he answers quickly.
The apartment is spacious, clean and great to live in.
I would not hesitate coming back.
