Alicia's apartment was perfectly located in Plaza Callao. My parents rented the apartment for 3 nights and were very content. The apartment is very clean and modern. Alicia was a great host and was easily contacted through cell and/or e-mail if we need anything the past couple of days. I recommend this apartment if you are looking to be in the middle of all the action in Madrid, stay just off of Gran Via, and be a couple of minutes walking from Sol.
