A "shared toilet" (or "shared bathroom") means that your individual guest room does not have a private toilet or shower located inside the room. Instead, these facilities are located in a communal area—usually a hallway—and are shared with other guests staying on the same floor. This is a very common setup in European "pensions," traditional hostels, and historic budget hotels. Typically, your room will still include a small vanity or "washbasin" (sink) and a mirror for brushing teeth or washing your face, but for everything else, you must leave your room. While this might sound inconvenient, it is a primary way to save money in expensive cities like London, Paris, or Tokyo. Most reputable establishments ensure these bathrooms are cleaned multiple times a day, and many have a "lockable" individual room containing both a toilet and shower to provide privacy, rather than a "stalls-and-curtains" gym-style layout. Always check the "Room Features" carefully before booking if a private bathroom is a deal-breaker for you.
