I don't quite know what constitutes a useful public review, as this was my first time staying in an Airbnb. However, some points of assuagement for whoever might be reading this:
1. Victor, Noemi, and Estela (who helped us to check in) are all gracious, helpful, and quick to respond.
2. This Airbnb is as it is portrayed; it's an affordable listing, clean, with plenty of space and a kitchen.
3. The neighbourhood, Boyle Heights, is well worth staying in. I'll avoid sounding like some kind of cultural anthropologist, but given that the area is currently undergoing and resisting gentrification, I reckoned it was a compelling part of Los Angeles to stay in (though, more valuable if you're bilingual).
4. The nearest Metro station, the Gold Line on Indiana Street, is about a 15 minute walk from the apartment. From there, it's easy enough to make your way wherever you might like. If you have a car, there's private parking on site so you don't have to trouble yourself with street parking.
I'd certainly recommend this listing without hesitation.
