It will definitely be a change of pace, but a good one to experience. Especially childless in your 20s. I grew up in the city, moved to the burbs for high school and college and then moved back to the city after college. It was an adjustment for sure but one that I’m glad I made. I love living a car light lifestyle and if I didn’t work in construction, would live a car free lifestyle. Living in a dense, walkable, mixed use neighborhood means everything is within a short walking/biking radius to me. No more dealing with traffic, frankly being forced to drive to the burbs on occasion now is just stress inducing. And because the he neighborhood we live in has been improving for the last 20 years, now we have 2 fantastic schools here (that frankly are better than most of the schools in the burbs) so now staying here even with kids is a quality proposition.
