This appears to be a very short room.
The ceiling doesn't look even, I'm thinking this is a second story room. Windows have thick edges, appear hand made. The softness of the edges of the ceiling imply plaster, so i'm going to say 70-100 year old house. Two windows (that we can see) very close to the corner is odd, but leads towards the second story room being in between a sloped roof or between two other spaces.
Shades imply that there is too much sun coming through the windows, this again implies that the windows are facing the south side of the building.
