This is one of those maps that as soon as you look at it you start figuring out what's going on there!
Let's see: 2 small 'dormitory' rooms, a larger chamber with a single bed, a colonnaded hallway, a room with a tiled(?) floor and another room with a corridor leading off. Oh, and a flight of stairs as an entryway.
What could it be? I'm thinking 'living quarters' in maybe a temple or monastery, with the senior member of the community having the large single-bedded room and some more junior ones in the dormitories. It could equally as well be a secular lordling's quarters or those of a military commander. The stairs may lead outside, whilst the passageway leads off to more public areas of whatever facility this is a part of... and then comes the fun of fleshing out whoever lives there and why our brave adventurers have reason to visit their private quarters.
I like maps like this, that start spawning adventure ideas rather than merely being the best fit amongst published offerings for whatever location you have in mind. It's all beautifully-drawn too, managing to be both clear and attractive. Nice work!
