TL;DR : Boulevard 1900 is a good option for students that want a quality living experience at an affordable cost that's close to ASU.
I've stayed at Boulevard 1900 for two years now back when it was called The Domain.
The front office staff are friendly and quick to solve any issues that arise. Always professional and they remember the names of the residents as well which is a plus. Packages are delivered to the front office so I interact with the staff often and my experience has always been good.
Maintenance staff are always helpful are respectful as well. While issues do arise in the apartment (which is as expected) putting in a maintenance request is easy and is usually fulfilled within 24 hours. Emergency maintenance is available as well, which is nice.
When I was considering apartments around ASU, I did a tour of all the apartment complexes around the area and Boulevard 1900 was the best priced given the amenities. Having my own private bathroom/room for an affordable price is fantastic. I went from a four-person suite with one bathroom dorm at ASU from an actual upgrade. From sharing two washer/dryers with an entire floor to having one in unit changes the game. Internet is decent (Pavlov Media is the provider) but works the best when you bring your own router. Cable has a nice variety of channels as well. There's even a storage closet. As for the apartment itself, room layout will vary, my room is a good size and fits me well. All furniture in the apartment is included which is a definite plus!
Pool is well maintained and has a small sand area which is unique. There's a game room, tanning beds, a small computer center, small gym, and even a rooftop lounge. That's a lot for the price!
Residents are all college students so it's as expected--parties during the weekends but usually things are quiet during the weekdays. On that note, the security that are around at night are needed to mitigate situations, they take their jobs seriously... Sometimes too seriously.
But overall a great place to live!
