Alicia and Carlos' apartment is lovely. In a great location, within walking distance of all the main tourist attractions. Both Alicia and Carlos were so welcoming and generous on our arrival. They provided us with lots of maps and advice on local eateries, and were so accommodating with regard to luggage storage. This was a great apartment to stay in for our Madrid visit. The only slight drawback was a lack of natural light, but the location and space made up for that. I would strongly recommend this apartment.
