Aryn's place is clean and quiet, and all amenities are provided. It's a great place for business travel in LA -- it's a short car ride from downtown but also pretty close to Koreatown and a highway. I appreciated the area around her house, especially the gated entrance, and her check-in/check-out process was incredibly easy. She was very quick at answering any messages, which made everything go smoothly.
There's not many things that are walkable distance though, but that's probably more common in places near the beach or West Hollywood. Food, groceries, etc, you'll likely have to take a car or ride-share to and from.
I wouldn't recommend this listing if you're here for fun and friends -- it's not a place that you can really kick back with friends like you would in a hotel room (and Aryn makes that clear in her house rules), especially since you share the apartment with your host/other guest.
Overall, I definitely think her place lives up the description in the listing -- no shady hosting or rooms, etc -- and it has a lot of features that made me feel safe when I was staying in LA. It's an ideal place for business travel, especially if you prefer a quiet, clean, fresh space away from the busy traffic and smoggy city -- while still being a short drive away from downtown.
