I loved staying at Olive's place! I've been to Mexico City a couple of times and have stayed in a few different neighborhoods. Olive's location is perfect, right on the border of Roma Norte and Condesa and walkable to so many amazing restaurants and cafes. It's also only 3 blocks from the Avenida Amsterdam which is a lovely 1.9km loop that's shaded by trees and great for running around.
Olive's building is almost brand new, has 24 hour security and a great rooftop pool. The gym is very good for an apartment gym (6 cardio machines, dumbells up to 40kg, boxing bag, medicine balls, kettle bells); so if you're a long term traveler it's easy to create a routine (I also never saw another person in there).
If you're working from here the wifi in the bedroom was 184 Mbps upload and 103 Mbps download which is more than any digital nomad needs. There's also a really cool Coworking called Haab that's a short walk away that sells day passes and nomad passes.
The kitchen was clean and stocked with everything I needed for the duration of my stay. The bed and bed linens were very comfortable and the shower was hot with great water pressure.
All in all I could not recommend Olive's place more!
