As long as you recognized that this is not a high-end resort sort of hotel, you will be fine.
However.
The normal issues:
I checked in for a nine night stay. When I arrived at the counter, a sign announced that the clerk was away and would be right back. If immediate assistance was needed, call the number on the provided phone. After twenty minutes, I did so. I was answered after a dozen rings with a rather brusque voice wanting to know why no one was at the counter (my question exactly). I checked in fine after that, although I was advised to return in two hours to pick up any dishes I wanted.
My room was clean enough, although there are several stains, a strange white residue, and large scratches on the walls. The blanket was also stained and had several long black hairs caught in it. No bugs though. I was given dishes but not a pan or the requested toaster. My refrigerator began leaking the last night of my stay and left a puddle on the floor.
The Strange Stuff:
Since there are two of the same hotel on the property, it was difficult for taxis to locate me. My first night of stay I received an unsolicited call from the same room number at the adjacent hotel, and he called me again early the next morning. Another person attempted to get in my room, I can only assume for the same reason. Also had someone attempt to deliver a pizza I did not order. Something needs to be done to differentiate between the two properties for room number purposes.
The wifi is terrible. It cuts out at random, stopped connecting to my phone halfway through my trip, and the speed is too low to watch a youtube video, probably to push you to purchase internet. I did not. I also noticed that every night, more channels appeared to disappear from the already paltry selection on the television. Not gone from the television, just completely blank when landed on. At least two disappeared every day.
If I return to Chantilly, I will likely look for a different hotel.
