En suite

An en suite is a type of accommodation where a private bathroom is connected directly to a bedroom via an internal door, ensuring access without leaving the room. 

En suite accommodations provide a higher level of comfort and privacy, making them popular in hotels, vacation rentals, and regular houses. 

In travel, the en suite bathroom is maintained as part of the overall room service. Hotel staff ensure regular cleaning and stocking of amenities, such as toiletries and fresh towels. The size, style, and luxury level can vary based on the room type and hotel star rating.
