I've stayed at the Signature before on multiple occasions, but when I went to rent a unit through the website, the prices were insane. Decided to check out Airbnb for the first time, and it was great: $200 cheaper than MGM direct, and that was with renting an extra night (required) that ended up being really useful (we didn't have to worry about checking out at 11am on Sunday). The room itself is great; we like to cook breakfast in the mornings and have some snacks on hand, so we made use of the kitchen quite a bit. More than enough of everything (pillows, towels, etc), so it worked well. I'd recommend it!
