I booked Ramon & Chicho's apartment at the last minute for an impromptu visit to Mexico City and could not have been happier to have landed here.
The apartment is in a quiet well-kept, eco friendly building. The space itself was sparkling clean, had great natural light and the view of the castle is exactly as described. It really felt like my home away from home during my stay.
Alejandra, the hosts' sister, was friendly and super communicative both before and during my stay, she was also thoughtful enough to leave a couple of beers and soft drinks in the fridge that were very much appreciated. I also want to call out the doormen who were great guys and super helpful as I did my best with my (rather limited) Spanish to elicit local recommendations and solve a minor issue we had at check-in.
To be transparent, the apartment does face a major road, but I didn't find noise to be an issue. It is also a bit away from some of the trendier spots in Condesa. That said, Ubers are inexpensive and plentiful; not to mention I found a handful of great gems nearby including great breakfast sandwiches at Clara y Ema around the corner, the rotisserie chicken at Pollos Ray a few blocks up (suggested by one of the doormen) and tacos from any number of the little holes-in-the-wall a few blocks to the right (north?) of the building.
All in all, I would enthusiastically recommend both this apartment and the hosts, to the extent that if and when I get back to Mexico City I will book this place again without hesitation.
