This place was a decent option in the San Rafael section of the city. Be forewarned: this area isn't as vibrant as other parts such as Condesa and Juárez, etc. I was hoping to find a little local flavor and I didn't. It was primarily residential and very sedate. Good for someone who will spend all of their time working.
The good: secured building, worker on site for part of the day, public shared spaces, wifi, hot water, well-furnished kitchen, washer-dryer
The not-so-good: space is MUCH smaller than it appears in the photos, a sketchy ladder with no railing and narrow steps for climbing up to the bed, a lot of dust kept us sneezing or clogged up while sleeping from the low exposed brick ceiling where the bed is, the bathroom is way too small--the toilet is flush against the shower door and you have to shift to sit, no curtain for the windows (only shutters) which means everyone walking by can see right in or you get no daylight.
There were also mosquitos at dusk. And though there are shared spaces, you're always right in front of someone else's door or window, so we didn't use them. Bummer.
Good space for someone who prefers to be shut studying or working. Maybe a good option for folks wanting a central place just for sleeping that is somewhat equidistant from downtown cultural spaces and the other trendier colonias.
