Although we did not meet Sonia in person, we had a very pleasant stay at Sonia's place. It is a large flat with 2 separate bedrooms, a large living room and a wonderful terrace where you can rest after a long day in Madrid. We were close to all the shops, restaurants and Grand via. Sonia was very responsive to all our questions thru the airbnb app or by text message. I would definitely recommend this place.
