4/10 Fair

There was a parking lot next to the property so that was good. Expect to pay $18-23 each day to park. It was so noisy. Not only could you hear your neighbor talking and hear the full conversation but the outside noise made it terrible for sleeping. I wouldn't stay at that location again.

The view of the city from our room was amazing. It's very close to the "Fashion District" which has a ton of great shops, restaurants, and much more. I would definitely stay here again.
