Roberto's apartment is lovely: it's beautifully decorated and well equipped with everything you will need during your stay. When we arrived, we found a bowl of fruit, a bottle of wine, and a refrigerator full of bottled water and a few Mexican microbrews. The building has a fascinating history (I wrote about it a bit on my blog: que buena onda dot com), and it's located in what I think is the nicest neighborhood in Mexico City. There are fantastic restaurants, cafes, bars, bakeries, clothing stores, etc. in walking distance. I would happily stay here again--in fact, I hope I will. (One thing you might need to know: the apartment is on the fourth floor--it would be considered the fifth in the US--of a building without a working elevator. It might be difficult for people with mobility issues.)
