Just moved into Amli Arista a couple of weeks ago. My opinion may change over time, but as of now, I'm giving this place 5 stars...no complaints. Front desk staff have been very friendly and attentive, addressing any move-in issues I've had. The community is very quiet and my neighbors are very friendly. There have been a few events held at the 1st Bank Center since I moved in, but they haven't caused me any issues or concerns. I don't think that I'd even know that they were going on except for the road signs that get put out asking event goers not to drive down the residential streets.
My dog loves the community park just a block away from my apartment. Once he gets bored there, there are about 10 other parks in the area within a 5 minute drive, including Central Park, East Park, Audrey Park, Purple Park, etc. There's always tons of parking available here at the complex, so that hasn't been an issue at all.
Plus, they have good, free, Starbucks hot chocolate in the business center. Also, I love that there is an RTD stop right here at the event center. When I have friends fly into town, they just have to catch the train to Union Station and then one express bus directly here. No more annoying trips all the way out to DIA to pick them up.
