Rafael is a very attentive host who will try his best to answer to all your needs. The flat is in a very central location and there is no need for metro pass since all museums and points of interest are within walking distance. The flat is not luxurious but will suffice to the undemanding traveler. It sleeps 4 easily + 2 in the living area if need be. It is very quiet in the morning, and surprisingly also quiet at night. The terrace is simple and could be improved.
Overall we had a great time in Madrid.
