The only problem I had was with the company in charge of the parking. When my QR code wasn't working, the person I talked to through the intercom in the lobby said I had to continue our conversation at the outside parking garage exit intercom. I had to stand outside in the cold and block the flow of other cars leaving to resolve the issue and then got lectured about how to use my QR code like I didn't know how. Other than that, the stay with Placemakr was great! The parking garage situation was the only reason I didn't give 5 stars.
