We were welcomed into their home, given free use of their microwave and fridge. They prepared breakfast for us every day and even had cola and orange soda stocked for us. The hosts are so sweet and warm; I highly recommend any and all people to stay with them.
In addition, you can walk to nearly any attraction within 20 minutes, and the metro is a 3 minute walk away.
We had a great time, and plan to stay here again if we return to Madrid in the future.
