Nice place to live in Oita?

Hello.

My job will require me and my family to temporary move to Beppu area (2 years at least). As Beppu seems quite a small town, for living I would rather prefer to move into a bigger center like Oita and commute to Beppu.

I have no clue about this area of Japan, so I would like to ask if anybody know some good areas to live in Oita or neighbor cities (ideally not more than 30 mins by car from Beppu). I'm looking for a quiet residential area, well furnished with transportation and services,

Any suggestion?

Beppu is not a small town with population of well over 100,000. It is touristy, but definitely has a character. Oita City, by comparison, is bigger but looks like an ordinary city (IMO). Personally, I'd rather live in Beppu than Oita City. I suggest you go see for yourself first, rather than deciding based on what you read.
