Yes, hostels are cleaned regularly, though the level of service differs significantly from a traditional hotel. Most reputable hostels have a daily housekeeping staff responsible for deep-cleaning communal areas like the kitchen, lounges, and shared bathrooms. In the dormitories, floors are typically swept and trash is emptied daily, but "turndown service" does not exist; you are usually responsible for making your own bed and keeping your personal locker area tidy. To minimize disruption, cleaning often occurs during the middle of the day (between 10 AM and 2 PM) when guests are encouraged to be out exploring. Because of the high turnover and communal nature, cleanliness is a major factor in hostel ratings on sites like Hostelworld; a hostel with a low "cleanliness" score is a major red flag for bedbugs or poor maintenance. Many modern "boutique" hostels now offer daily towel changes and even professional-grade sanitation that rivals mid-range hotels.
