Adolfo is very communicative. We were in touch throughout with whatsapp and he would respond in minutes. The fridge broke down and he had it replaced in a day. He was always available with answers to any questions.
The apartment is great for one person or a couple. If you have no problem climbing 4 floors this a good place, great location. It is in a culturally vibrant area. Lavapies is the upcoming alternative cultural neighborhood, with international neighbors. It has many theaters, an independent cinema hall, grocery stores, and many eating places. It is 5 minutes from Reina Sofia, 10 minutes from Prado. Within 5 minutes you can access the other vibrant neighborhood of Huertas. It is very close to the Atocha Renfe, if you plan to take train trips outside Madrid. It has a good mix of tourists and locals.
