We could not fault the apartment. It was spotlessly clean, centrally located just off the Plaza Mayor and a short (10 minute) walk from the Metro at Puerto del Sol. This metro stop can be reached from the airport on Line 8/then 1/then 10, Very easy to connect and about 45 minutes total journey.
We met Alberto (Consuelo's husband) at the shop below the apartment. He was charming and very friendly and pointed out a lot of places to visit on the map. Consuelo had left us a bottle of wine, spanish cheese and snacks to welcome us and Alberto took us through the apartment showing us how things worked.
Outside the apartment is a taberna and a minute walk away is Calle Cuchilleros which is a cobbled street full of places to eat & drink. At the end of this street is Mercado de San Miguel a converted market place with various tapas stalls and beer & sangria bars to sample. This was our favourite spot to while away some time with a crooqueta or cheese plate and a glass of rioja, it had a great atmosphere.
We loved Madrid, the people are friendly and it does not have a big capital city feel, rather more friendly and laid back. Shopping is good and only a 20 minute walk away to Gran Via (the modern shopping area with department stores and boutiques).
We would not hesitate to stay at Consuelo's apartment if we were fortunate enough to come back to Madrid. There are 94 steps up to the top floor so this would not be suitable for the infirm or elderly.
We did not cook but the kitchen is spotless and has everything you would need to prepare a simple meal. There is a washing machine and shampoo, shower gel, washing up liquid and cloths etc were provided as well as coffee. My daughter slept on the pull out sofa bed and said it was very comfortable. We have no complaints whatsoever and would recommend you try this apartment.
