Moving to Exeter - location advice

Hi all, another person looking at moving to Exeter.

I've just accepted a job in a local secondary school and am currently looking at places to rent (most likely for around a year until I can buy.)

I've seen some nice places to rent in Tiverton. Google maps says it's around a 30 min drive (on a Saturday).

Does anyone know if this route gets busier during rush hour (especially morning)? Is it a doable commute?

Edit: I'll be working on the east of the river
