Our staying at Sonia's apartment was excellent. Apartment is located in Chamberi - very calm and beautiful district of Madrid.
Metro, shops, cafe and restaurants are close to apartment. All famous sightseeings are not far, you can get to them by foot or on metro.
The apartment is very cozy and comfortable for 2 or 3 persons, with everything you may need for living and cooking. Heating in winter was important and it was ok.
Sonia is a great host, very attentive to guests. She sent us all instructions and answered any question very quickly.
Thank you, Sonia! We enjoyed our staying!
