This is my first review on yelp and its because this experience was great enough for me to get off my lazy butt to do it.
Just stayed at The Signature for my girlfriends 21st Birthday with some other friend. We booked a small suite through Jetsetter, but then wanted a bigger room. So we called LSI and they upgraded us to the one bedroom suite for free.
Using LSI is a bit different than actually going to the hotel because you don't contact the hotel for anything accept maintenance. Everything is done through LSI. Everything was perfect for us except for the fact we wanted to shower before going out to the clubs and we realized we didn't have any towels left. LSI housekeeping was already off duty and The Signature staff wasn't allowed to bring us towels due to some contract. That was the biggest flaw for me in the service. As for everything else is was perfect. I got free EARLY check-in and couple hours later check-out. I will definitely book through them again.
