Beatriz's place is in a great area to get to all corners of Madrid as it is very close to Chamartín train station and not too far from Plaza de Castilla bus terminal. The apartment is the top floor of the building so you have fantastic views towards the mountains on the balcony as well as a nice sunset if you're lucky. The place is big enough for 4 adults although the bed in the bedroom is only a double. The sofa bed is easy to set up and everything ready inside to prepare the bed. The flat has all the amenities you could need and we were very happy with our stay there. Thanks!
