We had a wonderful stay at Paula's home for our first visit to Madrid. Not only was the place as shown through the photos but the location was perfect for walking to many local eateries and sights! Definitely a great sized apartment for 2.
One thing we wish we knew before was about the hot water situation. Basically after our first night, due to being based in the center of Madrid, we found out that the hot water in the apartment is only good for reaches for two VERY short showers, then it is heated again within 20 min (per Paula, the hot water works allocation is based on the size of the apartment) so if you're into long hot showers, this may not be the most ideal.
But if you can get over that fact, this apartment really is well equipped and has everything you would need for a lovely stay!
