I've been in Toyoko many times and Yoshi's apartment is definitely one of the best. The apartment is exactly same as desribed. It's tidy, cozy and in a super quiet neiborhood. The metro station is 2 mins walk. Supermarket and the museum is also within walking distance. The host is also a great person with great communication.
I couldn't be more satisfied with Yoshi's apartment. Surely will recommend to my friends. Two thumbs up!
