You can't beat the location if you want to be in the middle of everything. A few minutes walk from Puerta del Sol, Plaza del Callao, Plaza Mayor, shopping, restaurants, etc. Very cozy, cute, and spacious enough for four. We ate outside for every meal, but if you like to prepare your own meals, the kitchen is fully equipped. You will have to walk up five flights of stairs, which we didn't mind. Fernando sent very detailed and precise instructions, so the check-in process, etc was all easy. He also provided wonderful recommendations of where to eat, transportation tips, etc. The only complaint we have was how hot it was in the apt. There's an AC unit in the main/living room but the cold air does not reach the bedroom. We had to sleep in the main room but even there the AC unit wasn't cooling enough at night. It might have been because it was extremely hot in Madrid last week. I am sure this is not a problem in the fall, winter, or spring. Other than that, everything else was very nice!
