If you need to be near the center of Mexico City, this is a very convenient, modern and stylish place to stay.
During the day, it is filled with light and very pleasant to spend time in. It's probably better for short rather than extended stays as the cooking facilities are minimal.
The restaurant on the nearby corner has live music in the early evenings during the week and until about 3 am on the weekends—it's best to be out of the apartment at these times unless you're a fan of a certain type of nostalgic Mexican songs.
The immediate neighborhood feels very corporate but charm (and sleaze) are just short walks away.
I had no trouble checking in or out and my communication with the host was always promptly answered.
