I stayed at the Hyatt Place while in Chantilly for a meeting and was pretty impressed.
Check in was quick and painless. Michael, gave me a quick tour of the lobby, breakfast area, snack area and bar. He was polite and friendly and got my visit off to a nice start.
The room was good sized with a large sitting area...kind of a mini suite. The sitting area included a wet bar, coffee pot, fridge and desk with plenty of electrical outlets. The bed was comfortable and the 42" TV was able to be viewed from both the bed and sitting area. Free wired internet access and wifi was available.
The bathroom was good sized and the whole room was spotless.
Breakfast was above average for free hotel fare. The breakfast sandwiches were nice.
I'd highly recommend staying here if you're in the area.
