This appartment was absolutely perfect: gorgeous, with ever possible need anticipated (restaurant recommendations, welcome pack complete with small cake, basic condiments, washing powder etc).
The host sent plenty of helpful information ahead of our stay (including a detailed guide to Madrid) and kept regularly in touch, responding immediately to any questions. He also went over and above helping us with our excess rubbish at the end of our stay. The appartment exceeded our expectations by far.
The location was perfect: within walking distance of all major attractions and across the road from the metro and a 24hr supermarket. La Latina, with its great restaurants is only a few steps away. We definitely recommend and would stay there again!
