I higly recomend Abel's flat, it is absolutely perfect. The flat is just like in the pictures, clean, calm and very well equiped. The location is amazing to discover the city, really close to the heart of Madrid, you will rarely need the metro or the bus. Abel is the nicest host, he is always ready to help and answer any questions or requests. We had the best experience in Madrid thanks to Abel's apartment and I would highly recomend it !
