Need advice on setting Unifi for home

I'd like to move from TP-Link to Ubiquiti. Today, I'm running one TP-Link router and running another TP-Link router in bridge mode upstairs. It's working very well. It's obviously not a mesh system - I named my SSIDs uniquely based on which floor it's coming from.

I'm looking at the Dream Router 7.

• Can I use the same simple design and purchase 2 Dream Router 7s the same way I have it designed today?
• Can the upstairs Dream Router 7 run in access point/bridge mode?
• Are there better designs that I should consider?

PS - I'm trying to get the great Cyber Monday deal where the Dream Router 7 is going for $229

Thanks!
