Yeti is pretty decent, and the 1.2 surprisingly good in town with a DSG box. Have one on hire at the moment (work stuff) and have to say I like it.
But... I'd rather have a MINI Dumpyman.
Yeti is soft and more difficult to place accurately on the road. The Dumpyman drives so much better. The diesel in the Dumpyman is the N47 BMW lump, but they haven't soundproofed as well as a BMW so it sounds a little rougher from the cabin.
Both have rear seats that adjust for angle and can be moved fore and aft to make more room as needed. Dumpyman has a flat load floor option which might help you, rather than the distinct lip in others.
Or you could do like me... MINI -> F20.
