Just used this on a 3 week hotel trip. Not too big, not too small. Functional, lightweight and stylish. Lots of internal pockets for valuables. Carried smartphone, camera & accessories; change of clothes, a book, rain shell, water bottle, maps. Didn't bring a laptop - but could have. Worked great on the plane and comfortable during the urban tours. Couldn't avoid a sweaty back but the mesh helped keep cool.
