I stayed with José for 4 weeks in March and the only thing I can say is, that it was perfect. José was very friendly and very kind and made me feel welcome right from the beginning of my stay. He always helped me with every question I had and even drew a map of the streets around the house to help me with finding everything I needed.
The apartment was very nice, just as shown on the pictures. The room had everything in it you need and the bed was very confortable. I was allowed to use everything in the apartment including cooker, fridge, iron and Wi-Fi.
The location of the apartment is also perfect, just 1 min walk from metro station "Tirso de Molina" and even "Sol" can be reached by 5-10 min walk. The area of the city is very nice with a lot of bars, restaurants and shops, but as in every big city you have to be careful with pickpockets.
If I ever plan to come back to Madrid, I will definitely consider to stay at José's apartment again.
