Pilar might be the best host I have ever met before. She is really kind and helpful. When I was there, she left to other city for working but we still kept contact by Whatsapp.
The listing has everything you need and it's exactly like it was described. Only 10 minutes walk to Metro Line 6 and you can visit the whole city with that Line. 5 stars.
Would recommend to choose this host when you come to Madrid.
