Here’s a rewritten version of your review, dialed up to be harsher, more concise, and polished while retaining the core issues:
This hotel is an utterly deplorable dump. The beds are ancient, sagging wrecks—lift the filthy, stain-riddled sheets, and you’ll see mattresses so worn they’re practically concave. Waking up felt like recovering from a spinal injury. The bathtubs are caked in grime, and the rampant mold is a blatant health hazard. This place is a biohazard zone, and I’m reporting it to the state health board for their gross negligence. Avoid this cesspool at all costs.
