This place is amazing. I recommend it if want to sightsee Madrid and you like the comfort of house instead of hotel. We were two couples with two kids, and it was perfect for them: plenty of space for them to play and we could also cook some meals (fully equipped kitchen included!). The only downside you get is the noisy Plaza Santa Ana by night, but you also get the lively neighbourhood by day. One word to Ramon and Marco, they were always available for us when needed.
