Yoshi's hospitality and house were perfect!
Three (3) most relevant pros are:
1) Location: Next-door (literally) to Sensoji temple; 10-minute walk to Asakusa subway station and Ginza line which goes directly to Akihabara, Ginza, Shibuya, among other places.
2) House: best kitchen I've ever seen with all modern appliances and fully equipped; full a/c and heating systems; fully equipped modern Japanese bath & toilets; comfortable tatami bedrooms; nice dining & living rooms.
3) Host: besides being able to practice Japanese with Yoshi, he is proficient in English and will answer efficiently to all of your questions. He made excellent dinning recommendations and went as far as providing snacks to us during our trip.
