Yes, medieval and Renaissance-era castles certainly had guest rooms, though they were very different from the modern concept of a hotel suite. In early medieval castles, "guests" of lower status might simply sleep on straw pallets in the Great Hall after the tables were cleared. However, for high-ranking noble visitors or royalty, castles featured "chambers" or "solar" rooms located in the more private upper floors of the keep. These guest quarters were often multi-purpose spaces where the guest would not only sleep but also conduct business, hold private audiences, and eat. As castle design evolved into the "palatial" style of the late Middle Ages and Renaissance, dedicated guest wings became common. These rooms were often the most decorated in the castle to impress the visitor and display the host's wealth, featuring tapestries (which also served as insulation against the cold stone walls), ornate fireplaces, and massive four-poster beds with heavy curtains to keep out drafts and provide a modicum of privacy. Hospitality was a serious social and political obligation in the Middle Ages, so providing comfortable and secure quarters for a traveling lord or bishop was a top priority for any castle castellan.
