It's very inexpensive, and sits at the foothills of the Sandia Mountains and Petroglyph National Park. It's almost always sunny, yet is rarely too hot for outdoor activities. As far as bike infrastructure goes it may just be in the top 10 for US cities. You almost need to go out of your way to not be an outdoorsy person here. It has a decent amount of restaurants, breweries, things to do, but if you're particularly starved for entertainment then there are cheap flights to Austin and Denver. Indeed, what makes Albuquerque really great is that you could use it as a nice place to decompress in-between destinations.
There are some downsides though. Crime is pretty bad, as is the poverty rate, but a lot of places here in the US are struggling with that right now. Truth be told the thing that annoys me the most may be the Gross Receipts Tax. Basically, if you freelance, your services are subject to what's basically a ~7% sales tax, only for services.
But given how inexpensive everything is, and how much I get, I can't really complain too much about the GRT.
