Scott couldn't have been a better host. From his home in Seattle, he sent us masses of interesting details about the area, Mexico City, etc.; and he responded promptly to queries by email. Luckily I had a little bit if Spanish with which to speak to his representative Gloria, because it might have been a little bit difficult otherwise. We had a good choice of comfortable beds, and opted for the one in the back, which was very quiet between 11 pm and 8am. The clutter in the flat gave it a real feeling of character but might not have been to everyone's taste, especially as it left very few surfaces for our own possessions. There was masses of lovely china, etc. but not much room in the kitchen for cooking. We stored all our food in the fridge as the cupboards were full.
The area was ideally placed for visiting the city but bear in mind that this is a huge city and the places you want to visit may be a long way away. We didn't enjoy the underground, which compared unfavourably to those in New York and London.
The area was as Scott described it, and felt very safe. However, this was our first visit to a rapidly developing city in a developing country and in retrospect would not have opted to stay so long- it was extremely polluted both from building dust and traffic. When we returned one night from a dance performance in las Bellas Artes, the Arcos de Belen was running with rats.

But if we did ever return to this city, we would be happy to return to this particular flat.
