I've stayed in about a dozen AirBNB's around Roma and Condesa and this location is the absolute best, just off of Av. Obregon and steps away from the pleasures of Roma Nte. The 6th floor apartment was spotlessly clean and comfortable, though it took a little practice to manage the windows/airflow when it was hot and sunny out.
Check-in and access was easy and the company was responsive when I ran into a small problem with the safe.
Each floor of the building features a unit on the street-side and another on the back-side and I would venture that the apartments facing away from the street are quieter. Even six floors up, there was a ton of street noise, particularly on the weekend. Noise-canceling headphones are a must. Nevertheless, would stay here again.
