We really enjoyed our stay at Condesa Nest. The location is perfect and quiet (considering how central it is and how loud CDMX can get on the busier streets) - walking distance to some of the best restaurants and parks in the city and generally easy access to everything else. Apartment was clean, and check in was seamless. Our host even arranged for a cleaning while we were there (we had the place for two weeks).
We were there with our 11 month old daughter and our host not only arranged for a pack and play for her, but even surprised us with toys! The apartment was great for traveling with a kid, but would have been equally as good if it was just me and my wife, or if we were with another couple.
We had one issue come up with the fridge, and our host had it fixed within a couple of hours of letting him know which was truly appreciated. Service and attention to detail were great.
We would definitely stay here again next time we visit CDMX.
