Overall, my group and I are happy with the stay. Juan was a more hands-off host, but was responsive to emails/text, friendly, and professional. The addition of the porter made this stay feel particularly secure.
The bones of this place are good: plenty of beds and comfy couches for sleeping/relaxing. We were a group of 4 and it was plenty of space with more room for a few more folks. There's a full kitchen if you need it. Very clean overall. And some cute-ish details—like the Frida art and the plant decor (although it would've been cuter if the plants were real). Like some other folks have noted, it is right next to a highway, which didn't bother my party, but I can see how it might bother some. It's something to be aware of. It's definitely well-located. In Condesa, near Parque Chapultepec, Zona Rosa, and the Roma neighborhoods.
My one criticism is that I think the photos are more attractive than the actual place. That's not to say that the place is unattractive. It's more like the photos look like a 10/10 but the place is more of an 8/10. Still good, but not quite the level of the photos. Also would've appreciated paper towel and an iron/ironing board, as these were not available. But I think that's something that can easily be addressed and based on Juan's responsiveness, I believe he would correct that right away.
Overall a 4.5/5 that could easily be a 5 with small improvements.
