Great location, great host, a great place to stay in Mexico City! I stayed in this apartment for almost a week during which I gave an online course. I can say that the internet connection is excellent as advertised. Overall though I would say the apartment is even better than advertised! The apartment is more spacious than the photos suggest and I found it very comfortable and good for working, in my case writing, preparing and giving a class. A friend stayed a couple of nights too, I slept very well in both bedrooms, beds are comfortable and there were adequate blankets. One thing that stood out was how the apartment gets a lot of natural light without having direct sunlight. I was here in January but I imagine it stays cool even in the summer.
The location in Condesa is excellent. There are a huge variety of places to eat nearby as well as plenty of local markets and food shops and I enjoyed cooking in the very well equipped kitchen. Parque Mexico and Parque España are super close. I would go to Parque Mexico to exercise, be outside, enjoy the sunshine and it's only a couple of minutes away. I enjoyed the relaxed vibe there, where lots of people go to exercise, chill, play, where there are various classes going on and where there was live music on the weekend. I would happily stay here again when in Mexico City.
