This Airbnb is very nice: modern updates, VERY clean, and very comfortable. Carlos, the host, is wonderful and responsive, as is his colleague who we met when we checked in.
If you have business in Hortaleza, for example a convention at IFEMA, it is very convenient. It is a 30min walk for just one quick Metro stop (Mar de Cristal to Ferria de Madrid). If you are visiting the greater Madrid metro area, there are two Metro lines and many bus lines to get you in to the city. Also, there is a small mall within 5 minutes walking that has a HUGE and amazing Carrefour supermarket that has outstanding foods (meats, fish, fruits, wines, etc.). We often bought fresh fish or meats, cheeses, and some wines and had wonderful evening dinners at "home." I recommend this place very highly.
