I always stay at Sheraton Mirasierra when I am in Madrid on business. The hotel is located a bit outside of town, but has really spacious and well designed rooms. Plus rooms have a large and comfortable king sized bed to sleep in.
Staff are professional and courteous, and it is rarely a queue to check-out in the morning or to check-in when arriving in the evening.
There are also plenty of delicious Spanish hams and cheeses available for breakfast, in addition to the standard continental or English/American options.
Spa facilities are excellent as well, although I rarely have the opportunity to use them when staying there.
