Will be heading to Japan next week. I've got 3 nights in Tokyo before I head to another prefecture.

Which part of Tokyo should I stay in? I'm lining up my dates for the 3 nights, and some of the leads live in Yokohama which I don't mind staying in.

Which area in general would be best to stay in? Looking for a balance of peace, nice greenery around maybe and still have cocktail bars while being decently close to the city
