Stop looking and book this apartment! I wanted to stay here for my entire 3 months but alas, other guests beat me to the punch! This apartment is absolutely beautiful and it was located smack dab in the middle of everything you could need. The apartment was beautiful and Rene even took care of providing small touches that really made my stay feel like a luxury experience. (Water bottles in the room, a iron and board in the room, maps, guidebooks, and toiletries). The kitchen was cozy but completely stocked with all the appliance you might need and he had filtered water ready as well (very important here!)
The room itself was HUGE and bright and the bed and linens were so comfy I barely wanted to get up and see the city. The room also had a fan, and giant windows with a lovely view of the neighborhood. And although we had to share the cozy bathroom, it was never an issue as Rene wakes early to work.
And the best feature of the apartment was Athos, the small doggy who was so friendly and chill. He basically greets you and goes to lie down (unless you want to play).
Also Rene was an amazing host, who communicated with me often and made sure I had everything I needed. This was the best welcome to CDMX I could have had.
I would stay here again in a heartbeat and highly recommend you to do the same!
