That's not bad. Under 55 is okay, but the lower the better in flower. I use a simple dehumidifier I got at Wal-Mart a couple years ago for $40. Try and get one with a drain hole so you can attach a garden hose, otherwise you'll have to empty it by hand every day.
Not to worry about the water droplets. I get that on a leaf or two, that are at the top of the canopy, during flowering as well.
