Changing hotels in tokyo ?

First time solo in Japan 🙂 🙂

Im staying in tokyo for 5 nights, Ive booked a hotel for 2 nights in akasaka, the next night Im planning on staying in Hakone, then back to tokyo for other 2 nights. Not sure if moving hotels to Asakusa, staying in the same hotel ,or moving to another area of tokyo?

Also, do you guys have any recommendations for stays in Hakone with private onsens?
