I'm also about your size, and I have a 52 cm Kona Jake that fits great and a 54 cm Surly Cross Check that is borderline too big, but I make it work with a short stem and short reach handlebar.

The thing is, without knowing what the frame is that you're considering, it's impossible to give you reliable advice. Monsterpile is right about top tube size being the key factor. The seat tube and head tube angles also play a part. For me, a top tube of about 540 mm is ideal. You can change about 20 mm either direction with a stem.
