The apartment is modern, clean, spacious, has fast wifi, all utensils and appliances for cooking / self catering. Location is central to be able to access many parts of Madrid city - we explored much of Madrid by walking from here (otherwise the metro is close by). Communication and checkin with Jason was simple, efficient and to the point. It is located on Calle de Atocha which is a main street that runs into the city, so if you are a light sleeper this might not suit you. But otherwise the apartment itself and neighbours were great.
