We have stayed at a least a dozen AirBnB's and this is easily the best one we've experienced. As digital nomads running a consulting business it's important for us to have a good space to work in. The light-filled main room with a large dining/conference table and reliable wifi was great. Even better was the view of the immaculate garden and the many days we were able to spend working outside in temperate weather surrounded by greenery, flowers, and two friendly cats.
After two previous stays in La Condessa, we found Carlo's Roma Norte apartment, close by the Fuente de Cibeles square, a superior location for easy walks to great restaurants. He pointed us in the direction of several restaurants that we hadn't yet experienced that were wonderful.
Finally, Carlos himself is the perfect host. Friendly, attentive and available, yet fully respectful of our privacy. His English is outstanding and he's a very nice man.
