Tokyo Accommodation Recommendations | Where is the most convenient place to stay for a free and easy trip?

Many friends ask these questions when they visit Japan for the first time:

✔ Where is the most convenient place to stay in Tokyo?
✔ Which area is recommended for a free and easy trip in Osaka?
✔ Where is the best location for business travel with great transportation?

Personal recommendations:

Tokyo: Shinjuku, Ueno, Ginza
Osaka: Namba, Umeda, Shinsaibashi

I’ll organize these later when I have time:
