Do yourself a favor and stop looking at other places-- this is the apartment you want.
I stayed in Rodrigo's apartment for 2 months and it was absolutely fantastic. First, the location is unbeatable. You're in in Condesa, the most beautiful neighborhood in the city. It's so green, there's friendly dogs everywhere, and great restaurants and cafes within 2 minutes of the building. Even within Condesa, this location can't be beat. You're half a block from a big grocery store, 2 blocks from parque Mexico, and right on the amsterdam circle-- perfect for morning runs! Then there's the apartment itself. It's a spacious studio that has everything you'd need: full, well-stocked kitchen, fast wifi (60 mpbs+; I had no issues whatsoever with streaming or on Zoom), a nice bed, a comfy chair for reading, 2 tvs, a laundry machine (it's a combined washer/dryer), and an outdoor deck. Lastly, Rodrigo is a truly fantastic host. Whenever I had an issues, he would respond to my message within minutes and have it resolved the next day-- at the absolute latest. He fixed things faster than I would have in my own house!
Don't hesitate any longer. Just book this place if it's available.
