Advantages of city living (around here):
We can walk anywhere we need to go, symphony, doctors, groceries, restaurants, park, etc. Could manage with no car.
Subway to airport is fairly convenient and cheap.
The park and botanical garden is next door, really helps with greenery. (I don't think I'd like living in any of the 30+ story towers away from the park).
The Beltline is about a mile away, Ponce City Market a bit further, a lot of bars that way with rooftops and breweries
This condo has a decent pool and gym and front desk for packages etc., and we travel a fair bit.
Most folks we see walking are much younger than we are which I think is a plus.
A ton of "ethnic restaurants" nearby.
Disadvantages:
Property is pricey, I could easily have my 20+ acres in NE GA with a pretty decent house on half what we spent
Property and sales tax is high (the latter is 8.9%)
Traffic can be a mess if we need to drive more than 3 miles or so
Some drivers get a bit crazy, more than a bit
Street noise can get high briefly, usually, stereos booming, loud exhausts ...
There are homeless folks around, they very rarely bother us, or even ask for money, which surprised me.
