Excellent apartment. Very modern and spacious with great bedroom, bathroom and open plan kitchen lounge. The best part of this Airbnb is the location, 2 min walk to Plaza Mayor and literally adjacent to cava baja (The best tapas Street in madrid). Tonnes of amazing restaurants within 1 minute walk including: Botin(oldest restaurant in the world!) and posada de la via, both of which are a must try!
Would highly recommend this apartment, very clean, secure with double locked building entrance and convenient.
