We stayed at Begoña and Alejo's studio apartment for one night as we had a connecting flight the next day from Madrid. The location was perfect, just 10 min walking distance from Atocha bus station where there is a direct express bus to and from Barajas Airport. The apartment is also 5 min walking distance from Sol, Plaza Mayor, the Prado Museum and right next to the metro. It is located in an area with a lot of restaurants but very quiet at night. The apartment was comfortable, very clean, had lots of natural light and a cool coffee machine! Begoña and Alejo were the perfect hosts. They are very nice people, were very hospitable and gave us some great touristic information. We would highly recommend there place!
