Overpriced and unjustifiably pretentious.
I thoroughly explored this place with some curious out of town friends who wanted to consider staying here. We walked around the entire property and also looked at a room. For the quoted rates, the value simply isn't there. As we walked up to the room they were showing us, the outdoor pathway actually looked no different than a cheap, run-down motel. The room interior was underwhelming. The bathroom was shockingly crappy-looking. The tub looked old.
The lobby looks interesting enough. For 5 seconds it kind of looks like it will meet up to its promised allure. But reality sets in when you look a little closer. The Mondrian is worth spending the time to walk around exploring it. It's not worth paying money to sleep in.
My friends decided to stay elsewhere. (The Biltmore, actually).
