It's a really charming two-bedroom apartment that's stylish and in an amazing location in the heart of everything you'd want or need in Condesa area, right near the park. It's the second apartment I've stayed in w Andy/etc, and was a great exp. Building echoes and can get a bit noisy at times and part of bedroom window that opens a bit is slatted and doesn't really seal tight, but I didn't have any problems sleeping or working from home. Hot water doesn't get very hot but works well enough for one shower. Shower heads are VERY short, though. I'm about 5'9 and had to duck. Wasn't a big deal but in case you're tall and it is for you, something to keep in mind. Lots of light in apartment.
Filter in kitchen is great and makes life much easier. Kitchen is well-stocked w cooking tools. Second bedroom is accessed only through the kitchen balcony, which is a bit odd but doesn't seem like a problem (it was just me, so can't say for sure). Because of that, back balcony door doesn't close/lock, but I don't think anyone could get up to the balcony so didn't seem like a big safety concern.
Wifi was fine for me working during the day.
