As many other reviews have said, this is a fantastic place to stay. We (my girlfriend and I) stayed a little over one week. The apartment is beautiful and clean, Eric is awesome and super helpful, and the location is perfect. The kitchen is stocked well for basic cooking, which we took advantage of, though there is plenty of great food nearby.

The apartment basically straddles La Roma and La Condesa, two very nice neighborhoods in the city. This is also one of the more easily walk/bike-friendly areas of the city. Lots to do any time of the day, and easy access to the metro or to buses for access to other parts of the city. Keep in mind that La Condesa/Roma are the more expensive neighborhoods in Mexico City, so prices are a bit higher in general.
