It's a bit unfair to rate a service on One single use that actually worked out, but here's the story: we left one piece of luggage for 10 days at the miami south beach location at the Mercur Grand Cafe. When we brought it, the attendant was not too interested, didn't check our order, didn't know that they did Vertoe and didn't want to give us the blue tag to close the luggage. In the end he did and then put the suitcase in the restroom. When we git back to pick up the suitcase, a different attendand didn't know where it was but found it eventually, but did not bother to check the tag against the picture (didn't even look). Then she asked why we didn't take both suitcases (there was another one, not ours). We left it (of course), but even though we got our suitcase this experience did not feel save - anybody could walk in there and say „I've got a suitcase with you“ and they just show you all luggage they have stored and let you walk out with whatever you like, not checking anything...? - not what we expected. Lucky for us our (not inexpensive) gear was still there. So: love the idea of this very useful service, but am abhored by the incompetence at this specific location.
