Alicia's apartment is fantastic! We were proud that we didn't use any public transport at all while we were in Madrid: the apartment is around a 30 minute walk from Atocha train station, and so close to everywhere else we wanted to go (Mercado San Miguel, Plaza Major, Royal Palace, Calle Cava Baja, museums etc.). The apartment itself is ideal for a city break. It's very stylish but also well equipped with everything you need. Highly recommended.
