What does it mean that the hotel window is located in the corridor or aisle?

1, the hotel window is located in the corridor or aisle, that is to say, the window in the room does not face the outdoor, but faces the indoor corridor or aisle. That is to say, there is an aisle about 50-60cm, with gaps between rooms and windows.

2. Due to the layout and scale of the hotel, the windows of some rooms cannot face the outside, which may lead to poor ventilation and high indoor humidity.
