Bistrot curtains: Easy to install and extremely versatile! Traditional bistrot curtains are an almost indispensable accessory for every home. They are installed directly on the window, on the wall above or on the window frame and can also be combined with regular curtains. On their own, they are the perfect solution for small rooms. They protect against unwanted glances, while letting light in and are the ideal solution for apartments with windows and not balcony doors.
