Top of the morning,
Roberto's place was awesomely close to the 3 subway line, which make north/south bound excursions gloriously accessible during rush hour. We did not make much use of the facilities in the building as Mexico City was a hub of opportunity and activity (we stayed a week) but the building was very well kitted out with just about every amenity you could imagine, and a couple you probably cant. A word to the wise for planning; you need to give 2 hours advance notice (to the front desk) when using any of the manifold hot tubs on the roof.
Roberto was an awesome host; we told him we would be arriving at 7am (we booked the place the night before for early arrival) and we actually made it to the apartment by 6am. None the less, he appeared promptly and politely and appeared to take delight at showing us around the building complex at the crack of dawn.
