My husband and I spent a wonderful week in Gemma's apartment.
It was as lovely as the photos, very comfortable and a perfect location. It is literally in the heart of the old city. Walked to the Reina Sofia museum, the Prado, Santa Anna Square & scores of wonderful restaurants and shops.
Most importantly, Gemma is a terrific host. She provided superb advice and was 'there for us' when my husband took ill for a few days. We have nothing but respect for her and heartily recommend her apartment.
