The positive: the apartment is an a great neighborhood - very lush, close to several parks and about a 30-35 minute walk from the Bosque Chapultepec. It is in a new modern building. Marble bathrooms, walk in closet in the master bedroom. There are lots of restaurants in Condesa and nearby in Roma Norte.
The negatives: the kitchen is furnished minimally for an apartment that sleeps four (four forks, four plates, etc). The WiFi is terrible. There were two of us and not all of our devices could be on the WiFi at the same time (what happens if you actually have four in your party?). The WiFi isn't even strong enough to use the apps (such as Netflix) that are loaded onto the TV in the master bedroom. We were in Mexico City for two weeks - part holiday and part working vacation so strong WiFi was important.
Finally communication with the management team was difficult from start (arranging the pickup from the airport that they offered as a service) to the end. WiFi was never addressed even though they said they would. The housekeeper came during our visit and the schedule wasn't communicated (we came back to the apartment one afternoon to find three people working in the apartment - mid cleaning there was no where even to sit for a couple of hours while they finished). I don't know if it was a language barrier (I speak very little Spanish) or the team is just managing too many properties but there was an issue here that affected our experience.
