Borja's apartment is amazing, very clean, bright and perfect for couple. The location is great and safe, near the Sunday's market and grocery store. There is a nice cafe opposite the apartment too. The check-in is smooth. We didn't meet Borja but he has asked his neighbours to show us the room so there is no any problems at all. With the small kitchen in the room so you can cook your breakfast and just open the window then you don't need to worry about the smell. I recommend this apartment if you come to Madrid!
