For what it's worth, TripAdvisor ranks it at 4.5*. Reviews are scant and a few look like they're from "insiders", but the 1 "circle" review from the German does seem to agree that it's a 3.5* star property, one that had a premature opening (before renovations were over) as well, a big no-no.

The other 1 "circle" review is from a clueless traveler who chose the Sheraton over Le Meridien expecting the Sheraton to be better (!!!) -- and did not mention the small fact that currently the Sheraton sells for half of the Le Meridien -- and at least one of the 5 "circles" reviews reads like a (fake) insider's post.

BTW, the pool is indeed tiny if they didn't expand it: photo.

I have a family stay at the end of May in USM ... still deciding which property.
