Spotless, cozy, modern, and close enough to walk to everything. We walked all over Madrid from here! There's a market on the corner, and the Javier Martin restaurant is a casual place that's open more hours, perfect for traveling families.
Towels were provided, but bring your own washcloths, no place in Spain (Europe?) provides them.
We didn't use the kitchen much, but everything was very clean. Love the decor!!
Check in was very easy, no problems at all. Very clear, thorough instructions.
