Julia is an incredible host, among the nicest I've had the pleasure of staying with.
Pros: The apartment is located in a great neighborhood, Oxxo across the street, El Pescadito a couple blocks, and some other great taco places a block away.
The place is HUGE, but feels a bit old. It's very nicely decorated, especially the living room.
Cons: The water pressure is very low - exacerbated by the fact it's a rain shower. Internet is good, but can drop off every now and then in the bedroom. There's a washer, but drying is on clotheslines in the bathroom (there is no dryer, the listing is incorrect). I had trouble with the overhead living room lights. The master bedroom is a bit dark even with all the lights on. The TV in the living room is too high (your neck will suffer), and the one in the bedroom doesn't have streaming/internet so you're left with cable tv. No HD audio (?).
With all that said, Julia is an incredible host, bringing you thoughtful snacks. She even had a video (like the in-flight security announcements) going over the property! She lives next door, so is always available to deal with issues.
