Paint for a small in-law unit (Interior and exterior) in East bay

[John D.]

What paint (primer and finish) would you recommend for a 300 sq ft in-law unit which would be used as a rental for 1-2 adults max. The size of the unit makes me lean towards lighter colors. 

Would be great if you could suggest shades and brands.

Also should I use the same paint for all the interior or have different for bathroom?

Thank you
