Antonio's apartment is in a fantastic location, is very secure and clean. We visited in December and the heating was excellent as was the shower. Beds were comfy and having the washing machine was very handy. It was lovely to open the large living room doors when the sun was out. As we visited over the festive period, Madrid was particularly busy and there was outside noise throughout the night but we expected this and did not hamper our stay at all. Would love to stay again! :-)
