Emilio´s apartment is amazing - probably one of my best stays with AirB&B ever. It is a very beautiful and incredibly clean apartment located in the best neighborhood you can stay in to explore Madrid. I am sure everyone would feel great and save there. Also, Malasana is just a few minutes walk from there, which is great for having dinner in amazing restaurants and enjoying the nightlife of Madrid. Important to mention is that it is completely silent in the apartment, throughout the day and also during the night. And even with 42 degrees outside, it was not too warm inside, and I almost had never used air conditioning which also worked perfectly when I used it.
The communication with Emilio was great - he is very friendly and always happy to help with anything you might need during your stay. I recommend this apartment to everyone who wants to have a perfect stay in Madrid. I will come back for sure.
