I had a very comfortable stay at Cristina's lovely bijoux flat, with her lovely friendly black cat! I did not stay in the apartment much as I was in Madrid on a course, but it was a fantastic location , so central and easy to walk to most of the important places and very near the metro. There's a lovely cafe downstairs from the apartment which is very handy for breakfast or a late night glass of wine! Cristina is very peaceful and pleasant and friendly person. I highly recommend this place . It is very small , but i also loved the quirkiness and old style of her flat.
