First off, if you see this, I can already assure you that you're on the right track. The images don't do justice for the apartment. It's much larger than it looks. The apartment is big enough for 2-3 people and encompasses a bedroom, private bathroom, living room, and full kitchen. Book if you're considering a stay in nice part of Mexico City. You will not be disappointed.
There is consistent hot water and a neat vintage styling throughout the apartment. I felt like a princess staying in a foreign country.
The apartment is within walking distance to the best places in Condesa and Roma, which includes high-end restaurants, bars, cafes, and even Starbucks. If you seek tourist attractions, it's also well placed enough to be only 10-15 minutes from it all. I also felt safe walking around at night, which was my initial concern. Alejandra speaks fluent English, so a huge plus for non-Spanish speaking foreigners.
I booked a very last minute stay, and Alejandra was able to get the apartment ready in less than 2 hours (including showing me the place) after another guest had just checked out. I got new sheets and great smelling linens and towels. She's above and beyond and always around to help. I even had access to her cell number in case anything ever got difficult. Nothing did of course, and she even answered my dumb gringo answers very promptly. I would highly recommend her as a host and her apartment. I came into Mexico City a stranger, and left with a friend. I should pay you jajaja. Gracias, Ale!
