Pros: Location, safety, comfort. We were walking distance from many coffee shops, a nice park, and a fantastic vegan taco restaurant. At night, if you get the munchies there's also a street food stand right downstairs. We felt very safe the whole trip, with the passcode lock in our apartment door and also key locked door to the downstairs parking garage entrance. The master bedroom had a very large bed, probably king sized. We also enjoyed using the living room in the evenings to relax and watch shows. The bathroom was unique with its modern design, a countertop with an old sewing machine underneath (so many cool touches throughout the apartment!). We even played one of their board games and felt very much at home in the city. Since we traveled as a couple, we used the extra smaller bedroom to store our luggage, which was very convenient. Our hosts were responsive over chat.
Cons: The only downside to the bathroom was that the water pressure was very low. A few past reviews mentioned this, but perhaps they weren't able to fix it (probably mineral build up and shower heads need replacing). Secondly, the master bedroom was very dimly lit - to the point where it was hard to find things at night. It only had one incandescent light bulb, which would benefit from being replaced with something stronger. I hope they can fix these two areas - that would make this place perfect!
Overall: This place is a great value, for the location, safety, and comfort. Also, if you want to really feel like you're in Mexico City, the colorful decorations and unique touches really make your stay special.
