Lucero's place is in a great location right next to the Parque Delta mall. For us this was very convenient as it made it easy to buy things like snacks and water without going far. There are also some great food locations in and around the mall. We called our Ubers to the mall everyday and they came in under 3 mins. Which is also about the time it takes to walk from Lucero's place to the mall.
The apartment was spotless, Lucero provided some basic amentities as well. I appreciate that she left us things like soda, water and fruit as well. She also responds to messages quickly. So should you run into any issues, you can be certain she'll attend to them immediately.
Her place is also pretty secure. It faces the highway and the main door to the building can only be opened from the inside by the security guard. The door to the apartment has a keypad so you dont have to worry about keeping a key safe.
On the other hand, it took us about 15 -20 mins to get to most places in the city. but I think this has mre to do with constant traffic is Mexico city than location. At night it was much faster getting to places. If you want to be able to walk to the Historic Center for example, that won't be possible staying here. However, given the price and how lovely the apartment is, I'd still choose to stay here again.
