Ulises was a great host! quick to respond. He even recommended some spots for us in Oaxaca (we were in Oaxaca prior to arriving in mexico city).
the location was PERFECT. right in the center of it all. you can easily walk anywhere in the neighborhood and feel safe. so close to restaurants, bars and shops. one thing that we did notice though, was that it was a little loud due to the bars next door. If you're a light sleeper, this might be an issue for you. and last, the beds were a little TOO firm. other than that, good airbnb and great hosts!
