The service might be offering accommodations with luxurious and stylish decor, paired with high-quality bedding made from charcoal-infused materials. Charcoal-infused bedding is sometimes marketed for its supposed moisture-wicking and odor-absorbing properties, which could add to the comfort and overall experience of guests. It seems like you may be referring to some kind of hospitality or accommodation service that offers "charcoal sheet" bedding along with fabulous decor. "Charcoal sheet" could possibly refer to bedding made from charcoal-infused fabric or sheets with a charcoal color. Remember, as this was a speculative interpretation of the phrase you provided, it's always essential to conduct thorough market research and understand your target audience to tailor your services effectively. Additionally, any changes or developments in the hospitality or home decor industry beyond my last update may affect the viability of this concept.
