The flat was exactly as shown on the pictures, very modern, recently refurbished and equipped with anything you might need during your stay. It was also immaculately clean. Both beds are incredibly comfortable and that was great to have after long days of walking around Madrid. The bathroom is fully equipped and the shower has very good pressure. The only thing we missed was some kind of heating in the bathroom. Location is perfect, being only a 10 or 15 minute walk to Puerta del Sol, the very centre of Madrid. Communication with Carlos was smooth and quick, he was very attentive to make sure we felt comfortable at his flat. We also appreciated his flexibility both at check-in and check-out, as this made our trip a lot easier! Overall, an excellent experience, I would definitely stay again at this flat.
