Location perfect, easy transfer on the Metro - station only yards away - fantastic communication - could not have been more helpful - excellent place to stay - could not fault it. We had a superb time in Madrid and cannot wait to visit again and would definitely stay at Carmens. Many thanks also to Sol who arranged to meet us earlier for bag drop off and gave us a potted history of the building and some tips to help with our stay. Spotlessly clean and facilities excellent especially the showers - hot and fast flowing! Very comfortable beds.
