We loved our stay in Abel's apartment! It's spacious with all the amenities you need for a short or long stay (full kitchen, two bathrooms, washer and dryer) and it is in a wonderful part of town. There is a Green Corner (health food store/restaurant) on the same block, tacos and pizza available late night, and numerous delicious restaurants within a 5 minute walk. Two of our favorites were La Posta (delicious, really reasonably priced fancy pizza and pasta, if you've had your fill of Mexican food) and Los Amantes, a French-style cafe with delicious Tumeric Ginger Lattes and the best chilaquiles I've every had in my life. It's also a short (10 minute) walk from El Comer, a huge grocery store with all kinds of international products on the second floor if you're missing something from home. About a 20 minute walk (or short Uber away) is one of the fanciest malls I've ever been to - Oasis Coyoacan. It's also a 10-minute walk from the main Coyoacan square, which is an awesome place to go hang out and people watch, or go to the cool artisan's market or food market. It's a 20-30 minute Uber from Roma/Condesa/Historic Center. Also there are multiple pharmacies on the block so you can get anything like that you need super easily as well.
We really couldn't have asked for a better location to explore the city from, and we felt totally safe 100% of the time, even walking around at night. The only slight downside was the closest subway stop is about a half hour walk away, but Uber is so cheap and readily available that we really didn't miss it.
I also have to say that Abel's communication was fantastic. He was always checking in on us and making sure we were okay. We were living in this apartment for both big earthquakes in September 2017, and in addition to immediately sending us texts to make sure we were okay, the apartment itself held up like a dream. It's obviously very well built and we were told part of the reason it handled so well in the quakes (barely anything even fell over, just one or two toiletries in the bathroom fell off the sink) is that it was built directly onto lava rock, instead of the sandy lake bed that much of Mexico City (the Roma and Condesa neighborhoods especially) are built on.
So if you want a large apartment that's centrally located with a ton of stuff in easy walking distance but don't want to be surrounded by other tourists - and you want to feel safe in case of an earthquake - considering staying here! :)
