Great place.
My review would really be complete with that but I'll add details and caveats for those who appreciate depth and nuance.
Coyoacan - if you're looking for a place here then you probably already know - this is a living, vibrant, energetic neighborhood where people like to be alive and let their neighbors know it. Yes, there will be un-muffled VW bugs racing up the MAQ. Yes, there will be a yard party a block over that they likely won't invite you to. Yes, there will be police and ambulance sirens and roaring motorcycles, but after an hour on the rooftop terrace sipping good tequila anejo that you bought at the the "big name store from America" two blocks away for less than half what it would cost you in the States, you won't care at all. That terrace was absolutely perfect, rain or shine.
Antonio & Maria have created an urban retreat that you want to be in. The space is well-designed with everything that you would want in a vacation escape.
The kitchen is well-equipped and the table & bench are comfortable and roomy. The fridge keeps your beers cold and the induction top gets your eggs fried up nicely. Not much more than you can ask.
The bed is really comfy. I like a softer mattress and my wife like hers firm, but we both liked this one. Weird, but I'll take it. The bathroom is spacious, and the rain-shower is nice. There is a nice ventilation window that keeps it from ever getting steamy and also allows your clothes or towels to dry out nicely.
The star of this show, though, is the terrace. Climb a short flight of stairs and you'll see what all the hullabaloo is about. No, you can't see the Eiffel Tower, the Pyramid at Giza or even the Zocalo, but you can breathe in the essence of Coyoacan. From the guy practicing the trombone (keep at it, amigo!) to the street sounds to the mariachi band warming up to the smells of the bakery downstairs to the waft of jacaranda that are everywhere in the spring time. That terrace is money.
The hosts are incredible. Need a coffee? They got you. Dinner? They have recommendations and all of the ones we went to were great. COVID test people didn't email your results and your plane leaves at the crack of dawn? They will make a call and it's all good. You won't find better ABnB hosts on the planet.
I've recommended this place to my family, and I'll recommend it to you.
