I have stayed at dozens of places around the world and in the states and this was by far the best experience!
First I'll cover the space itself. This is a lovely modern space that's also very comfortable. It's clear that the host carefully thought about everything a guest would need to be comfortable. The fridge was stocked with large bottled water, sparkling water, beer and hard seltzers to purchase, which was so convenient. After 24 hours of travel due to delayed flights and re-routes, it was SO nice to walk into a place that had a stocked fridge saving us a trip to the store when we were exhausted. The beds and furniture were comfortable and the space was well-maintained. The location is PRIME! This is in the heart of Roma Norte and walking/short uber to Condessa which is full of delicious food both fine-dining and casual. Also really close to Chapultepec. Felt very safe walking around and the security guards are all super friendly.
Now on to reviewing our hosts. Fernando is AWESOME! Even before we arrived, he checked in with us to make sure we had everything we needed. He sent great restaurant recommendations and all of our messages had responses within minutes. It's so reassuring to know that you have a local available to help you when you're traveling to a foreign county. Our hosts even went the extra mile when we forgot some clothes at the AirBnB. We were already at the airport and our host handed our forgotten items to an uber driver who delivered it to the airport! I can't speak highly enough about the experience. The only possible critique I can think of is that the road noise can be a little loud in the evenings, but that's the price you pay when staying in a hip area. Highly recommend staying here!
