Overall: Absolutely amazing. To be honest, when I first saw Jorge's place on Airbnb, I thought it was a little pricier than some of the budget places listed. I'm so glad that I booked anyways - the value was beyond comprehension. 5/5
More details:
Location: Jorge's place is literally a 3 minute walk from the Atocha station - whether it's the Metro, the Cercanias urban railway, or the Renfe AVANT and AVE trains, the entrance to all of these is literally on the same street as his apartment. You can't get any closer. The apartment is also located near El Retiro park, a major attraction of Madrid. Also located near the famous museums, The Reina Sofia and El Prado. 5/5 for location.
The Apartment: Jorge's apartment is in a very secure building, the other residents seemed very polite and kept to themselves. The apartment as a whole is very spacious, and Jorge allows you to use his kitchen freely. He is often even happy to share whatever milk, snacks, or bread he has with you! 5/5 for overall apartment quality.
The Room/Amenities: The room is the most spacious Airbnb I've ever had. A giant window for natural light during the day, with black-out style blinds to come down at night, offering maximum noise and light insulation for a great night's sleep. A roomy bed that can fit two comfortably, or total luxury for one. Clean sheets and bedding. The bathroom is private to you, with a clean sink, sparkling toilet, and even a bidet if you wish to go the European style. The shower has good water pressure and warm temperatures. 5/5 for room and amenities.
The Host: Jorge is the expert of hospitality. He is so genuinely kind, ready to go out of his way to make your stay in Madrid the best. He offered me to take his bicycle if I needed to go around the city, would always help me plan out the most efficient route to go visit a place, and would always personally make sure that I made it back safely. This was all done with the most polite demeanor, not making it uncomfortable or intrusive at any point. Jorge is genuine and a wonderful person. 5/5 for host hospitality.
