Great place - very peaceful and clean and in an awesome location (even though it's technically in doctores - some parts of which have a bad reputation this place is very close to Roma Norte and is safe). Close to niños heroes station so it's easy to get south to explore Coyoacan. Really good street food nearby too!
Roberto was by far the best host I've ever had on Airbnb - super helpful, immediately contactable, provided heaps of good tips on where to go, and was very tolerant and flexible with our arrival when our bus was delayed coming into the city.
I'd stay here again in a heartbeat.
