The apartment is refurbished and in an absolutely great location. There are double patio doors so there is no street noise. The apartment is well equipped and comfortable. Great appliances, including a washer and dryer. There is an elevator.
I would highly recommend this apartment to others visiting Madrid.
The location is roughly 600 meters from the Atocha train station which links you easily to the airport, high speed train, commuter trains and metro.
Further, the Plaza Mayor and Puerto Del Sol are also about 500 meters away. The three big museums are all less than 800 meters away.
