Location, location, location. The apartment is located in the heart of Hipódromo which is funky, hipster neighborhood adjacent to Condesa, and it's lovely and easy to get around in. I felt perfectly safe as a woman traveling solo and there were plenty of tourists around. The parks, cafes, tree-lined streets and promenades are fabulous. The apartment itself is a little funky just like the neighborhood it's in. I traveled alone but it could easily accommodate two couples or a small group. The building is older and there is street noise and construction going on downstairs, but Mexico City is loud in general, so don't expect complete silence. If you've stayed in nicer hostels, the apartment has that vibe. Things aren't perfect but it's a great value. I'd recommend Lucas's place with those caveats.
