Romantic break for a few nights outside Madrid, Spain?

Hi everyone, My fiance and I (he's Spanish, I'm American, but we live in England) are tying the knot in Madrid this Spring. We are planning a bigger trip abroad later in the year, but still want to go away for a few days to relax and recharge after the celebrations. Do you know of any countryside hotels with nice amenities an hour or two outside of Madrid where we can escape for a few days? Toledo is amazing, but we've already been and so were thinking of something a bit more secluded. Thank you :)
