Traveling to Berkeley with kids--looking for a kid-friendly hotel with adjoining rooms

Hello!

This spring I'll be visiting my brother in Berkeley with my two young children. I'd prefer not to stay in a VRBO (and def not an Air BNB) but in order to not lose our minds we need to stay somewhere with adjoining rooms.

This is proving surprisingly hard to find, and a lot of the hotels don't seem very kid-friendly in general. We don't need anything super fancy; anything clean with adjoining rooms will work.

My brother doesn't really have any guidance here, so I would be very appreciative if one of you do!
