We had a great stay at Cristina's! It's the perfect location for a Madrid City stay, you can easily walk and/or catch the Metro to anywhere you want to go and there is great food, shopping and markets on the doorstep. Cristina was very friendly and easy to communicate with - the check-in/check-out was seamless and Cristina kindly allowed a late check-out. The living room is lovely - very spacious and bright, making for a relaxing and chilled group stay. Our only snag was that the air con broke and it was 37 degrees - my 70 year old mum and Aunt struggled in this heat. Would still highly recommend Cristina's apartment and hospitality :)
