My boyfriend and I recently stayed at Rocio's apartment for our first trip to Madrid. This is a cute apartment very centrally located and within walking distance to tons of restaurants and bars. The place is small but had all the amenities that made it perfect for our stay, including a washer/dryer, small kitchen with a refrigerator and microwave, and air conditioning. Rocio was incredibly responsive and gave us great restaurant and bar recommendations. I would definitely consider staying here again the next time I visit Madrid!
