I spend about a month and one week in the apartment. It's perfect for one. there is has a good kitchen, you can enjoy a nice hot shower, big tv for a lazy time. Good natural light but nearly no direct sun sadly (a few min depending on the sun angleand time of the year). The rooftop is the spot to get some sun. I went regularly, no one was there except once. The location in the city is great. Every Sunday there is a big open air market 5min walk in Calle James Sullivan. The Walmart is handy. The is also a bakery nearby, next door to the nakery a place to buy products without packaging named Graminea.
It's a safe area. I walked back from zona rosa/reforma a few times at night without any problem.
The communication with Marcela was great, we didn't meet but the concierge gave me the keys when I arrived. I also could do a late checkout with was nice with my late flight. Thanks again for that. If you have the budget, go for it! :)
