Tl;dr would be fine for a short weekend stay, but not great for longer term stays when you'll be spending significant time in the unit working remotely or otherwise.
It's an interior unit on the first floor of the building, meaning that all the windows face the inside of the building. Disconcertingly, the windows in the living room face the main elevator, so you can see people walking to the elevator and they can see you. A few times a week, cleaning people are working on the windows. The unit gets incredibly little natural light and the bulbs in the living room are very low wattage, so the apartment is extremely dark even in the middle of the day. It also backs onto a very major street, so you get a lot of noise from cars and trucks at all times. The pictures in the listing are not current (there is a big stereo system pictured that is not currently in the unit, and some of the art is different).
Pros: very clean. Secure building. Great for watching movies (excellent couch and television). Good wifi. On the southern edge of Condesa, bordering Escandon. Close to Molino El Pujol. Easy communication.
