It was seamless, the "conserje" at the gate had a sealed envelope with our keys, the apt is just as pictured and very comfortable. And the very good Metro system is right at the gate just a few yards from the bldg. giving you the entire city at your door. Cecila has a sites and sights guide directing you from the apt. to all the interesting places to see. We had a few questions and email gave us very quick responses.
