Super sweet apartment. We loved the way it was decorated and it had everything we needed (even a little espresso machine with everything we needed to use it).
Antonio was also an excellent host. He was very prompt with his communications and was really willing to go out of his way to make our experience great!
Also, you cannot beat the location. In walking distance to everything we wanted to see (Prado museum, royal palace, etc). Excellent food and coffee on every corner around. Plus the flea market on Sunday mornings was literally on our street!
We will def try to book this place again next time we are in Madrid :)
