We enjoyed our stay at Viadora. The apartment is well located and pretty well furnished. There is a lovely roof terrace, and the furniture was great. The beds were comfortable (even though the pillows weren’t really to our taste), the kitchen was well equipped, and the bathrooms were great.
But we also had a few niggles:
1.	The air conditioning could be noisy at random times
2.	The a/c in the main living room leaked and I had a place a bucket under it to catch the water
3.	We noticed a rather bad eye-sore outside the window of the 2nd bedroom.
The company responded to our messages but the issues weren’t resolve in the few days we were staying there.
I’d highlight that the building is very near highway. This wasn’t a major issue, but it did make using the roof terrace during the day less appealing and we did get noise from the road at night.
Overall, my impression of Viadora is positive but I might be inclined to choose a different location for my next visit to Mexico City.
