Julia's place is as described and shown on her advertisement. it is compact but really nice and clean and it is all very modern. I really liked staying there although if you are like me and are a light sleeper, the noise of the traffic is really loud so I highly recommend bringing some ear plugs.
I would have liked a bit of local information. perhaps a map and some local places to check out, like a lot of other Air BnB hosts leave in the room, but Julia was quick to respond to my questions throughout my time there so I appreciated that.
It's a short taxi from the main historic area and there are some bars and restaurants nearby to check out so it's a good place to spend time in Mexico city.
