An older "first-ring" suburb of Milwaukee. Came for the job, but came to realize it is a gem. I grew up in a large eastern city, and this seems better to me in many regards. My municipality is about a square mile, with easy access on foot to: restaurants of all levels, bars, post office, grocery store, services, churches, specialty shops, etc. We have excellent public schools. The community is very friendly and tight, yet welcoming.
The housing stock is mostly 1910's-1940's, with delightful older homes, but with newer condos and apartment buildings, too. I live 1.5 blocks from Lake Michigan, and about a mile from the Milwaukee River. We keep a sailboat in a County marina about 15 minutes away. There are numerous parks, and hundreds of miles of walking/biking trails. You can get downtown in about 10 minutes by car, 20 minutes by bike or bus. The local joke is that
everything is 20 minutes away, i.e., I can get to just about any part of the greater Milwaukee area in about 20 minutes by car. We have two major sports teams, plus we lay claim to the Packers, so let's just say 3. Good healthcare systems.
I do most of my shopping on foot. I have a very large grocery store 7 minutes away, a Walmart 20 minutes away, and an Aldi's and a local co-op (sort of Whole Foods-ish) 25 minutes away, all on foot. I can (and sometimes do) even walk to Home Depot or a local hardware store (~40 minutes).
Cost of living and housing costs are moderate. I live in a quiet, leafy neighborhood in a 4500 sq.ft. home, 1.5 blocks from the lake, that costs less than $1M. However, I can easily walk to homes costing ~$5M and ones that cost ~$80k, as well as affordable apartments and duplexes.
In the summer, there is no end of festivals, parties, events, etc. (Summerfest is one of the largest music festivals in the world, and Irish Fest is the largest celebration of Irish culture in the world. We also have Polish Fest, German Fest, Mexican Fiesta, etc.) I can walk to my local Farmer's Market with scores of vendors. There are numerous biergartens; I put together an itinerary with about 8 or 9 stops along a rails-to-trails bike path. (I have been to all of them by bike, but not on the same trip!

) Our county park system has numerous golf courses, including one that used to host a PGA tournament. I can go to the quiet local beach on Lake Michigan or to the lively, raucous one in Milwaukee with many volleyball courts and a tiki bar.
Of course, if you need something that Brewtown is too small to deliver, Chicago is only 90 minutes away.
Cons: Winters are tough. I don't mind how cold it gets, but I do mind how long it gets cold. However, we are on the "correct" side of the lake, in that it is generally sunny in the winter. The cold, dry air is not so bothersome, better than gray skies for months on end. I do look forward to spring each year, however.
Taxes are somewhat high, but at the local level we get excellent services and schools in return.
