The property was decent, and maintenance and cleanliness were fine, but it's not been updated much, and they were short staffed. The room night price seemed high relative to value. Would recommend, as the staff they have is enthusiastic, and the location is in the midst of everything South Beach.

I only stayed one night but overall, Creekside was better than I was expecting. For an old keys motel type inn, it was very clean and well kept.

First time visiting LBTS. Our room was first floor, beach front and was walkable to all of the restaurants, bars and shops. Location, cleanliness, service of front desk staff, all excellent! The only bit of disappointment was Backflips, the onsite restaurant/bar. This has the potential to be a gold mine, but staffing is key. One day we ordered the bacon cheeseburger (a menu item) and we received a plain cheeseburger with nothing on it. Sent it back and then received another that did have all of the fixings….but no bacon. Fries were old and cold. Told server. All we got was and apology and the bill for $16. They also advertised happy hour from 9-10 pm. Arrived at 9pm and the bartender displayed an attitude like “”why would you come here so late?” Like we were interrupting her ability to close so she could go home. Don’t advertise a happy hour at that time if you don’t want customers! They missed out on a lot of our business for that week.
