We stayed here for the last night of last year’s holiday in Spain – it’s pretty convenient for Madrid’s Barajas airport. The parador is based around an old convent but generally is very hi-tech and modern, almost too much so: a panel at the bedside allowed you to switch off the lights in the whole room, but you couldn’t have one bedside light on without the other being on too – not really a technological advance! The whole place was completely accessible apart from, I think, a tiny step down into the courtyard but I might be misremembering and the bedroom had both a wet-room style bathroom and also a bath with shower over too.
It is in the town centre and has a courtyard rather than any gardens so not as relaxing/get-away-from-it-all as some but peaceful nonetheless. The staff were pleasant, the food good with plenty of choice at breakfast and the town is very pleasant and historic too. I would definitely recommend this for a brief stop.
