I had to add a day to my stay, so this is the review for the extra day--same experience, obviously.
Consuelo and her boyfriend, Juanma, were very friendly and helpful guests. They consistently helped with great recommendations and were in constant contact whenever I had a question or needed something. I consider Juanma to be a friend after all the great conversations we shared while smoking a cigarette on the roof area.
The apartment was clean and was furnished with everything one would need for a comfortable night's rest. The kitchen was perfect for making breakfast, and the couple even grow their own tomatoes, if you want to have a traditional Spanish breakfast of toast, olive oil and tomatoes. The metro station is literally across the street and amazing restaurants, both touristy and non-touristy, are a 7-10 minute walk away.
The price, location, apartment, and hosts make this listing a steal. I would gladly stay again if and when I am back in Madrid.
