I have been renting for the past 12 years, and I can genuinely say that this is the best apartment complex I have ever lived in for multiple reasons.
First, the apartment itself is very nice and spacious, especially for the price relative to the surrounding markets - I couldn't be happier with it. The amenities are plentiful, fantastic, and well kept. For example, their gym actually has a olympic bar, which I've never seen an apartment have before! You also receive discounts at the surrounding businesses; e.g., 20% off at TCBY. It's fatteningly awesome.
Second, but just as important to the first point, is that the management is outstanding - in particular, Jessica! I moved to Colorado from overseas and she made this transition exceptionally easy, despite some bumps along the way from my end. AMLI was more than accommodating and to a degree that I've never experienced before from any other complex.
This alone had warranted a 5 star, but since then a few small issues have arisen: mailbox key not working, the kinks of a new package delivery system (which is awesome and allows for 24/7 pickup), a neighbor not complying with community requirements, etc. All issues have been promptly, kindly, and professionally taken care of.
Third, the location is very nice - you have easy access to the RTD, US36 bicycle path for quick access to both Boulder and Denver; groceries, shopping, cafes, etc. are within close driving distance; and there is a brand new hospital only about 5 minutes walk away.
The 1st Banking Convention Center is very close being at the perimeter of the AMLI property; however, there have been a few events since I've moved in yet the disturbances were surprisingly minimal, if at all, and I live in an apartment as close as it can get to the CC. For those with cars, AMLI has terrific parking enforcement, especially during events, and you'll not have to worry about parking issues (e.g., someone stealing your spot).
If I could give a rating of 6 stars, I would.
