Great location a few blocks from Plaza de Cibeles. A metro station is a 5 minute walk, there is a small grocery store just next door.
The checkin was well coordinated and a person was waiting for us when we arrived, to show us the flat and the amenities.
The communication with the host was very good. They always responded quick, and both the checkin and checkout processes were well organized, with timely and clear instructions. I would definitely recommend this place.
