If you're coming to Madrid, don't hesitate to stay at Oscar's! His flat is clean and comfortable, the bedroom is fantastic, and is exactly like the photos. His WiFi works well, and he gives you full use of the kitchen and bathroom and your own set of keys. The location is amazing; right next to the bullfighting arena, and has several quick options for getting to the rest of the city and airport. Best of all, Oscar has great tips for what to see while you're in Madrid, and he will let you know what is worth your time and what to skip. I wish I could have stayed longer!
