I moved to Four Peaks two years ago. I live in a townhome that doesn't have the upgrades. The space is very nice. Great closets! I also have an attached garage which I love. I read the other reviews and I agree that you can hear things like the water running between homes and your neighbors is they're too loud; but I also think that is part of living in an apartment complex so it doesn't bother me.
The maintenance guys are great! They fix work orders within a day or two of me calling. The girls in the office are really sweet and one of them watched my cat over christmas because I was out of town.
As far as safety, the complex isn't gated but it doesn't need to be. The town is very quiet. Fountain Hills is beautiful, seriously and the mountains are amazing!!! Great views for sure! Props to Four Peaks!:)
