I never expected how well-located this apartment was but it was really at the center of where one could go to easily by walking. We were so near the major museums and to the Plaza de Santa Ana, and Plaza Major (and the Mercado st Miguel) - and so convenient for public transportation. It is also near some very fine eating establishments, close to the Mercado Anton Martin where you will find a lot of food stalls. The apartment was lovely and the decor was smart, minimalist and stylish. We loved the use of space and interiors. It does look out on the Calle de Atocha but the sound proofing is excellent (it has air-conditioning - so no worries if you shut the glass doors). We didn't mind the noise and opened the doors - it is a lively city. Jason is a very professional host - non-intrusive but will respond quickly and helpfully. I would easily stay here again if ever in Madrid and recommend the apartment to all my friends.
