This room was pretty much as described. The location in the arts district was perfect for my purposes (attending a show at the Moroccan Lounge). It's a short walk which feels pretty safe. There are great restaurants around, all walking distance.
The apartment itself is clean but furnished very cheaply. Served my purpose, but for the price, it was a bit disappointing. Comfortable enough bed, but no sheet between the comforter, and pillows we too firm. It also doesn't get very dark in the room. I cannot speak to the sofa bed, but the sofa itself was fine.
Host was very quick to communicate, but there were a few miscommunications along the way due to dealing with several people. Nothing left unresolved, however. They do ask you to switch to communicating over and outside app (Whats App), which I do not like. But they will only send you the check in information this way. However, once received, check in info was smooth and clear.
Overall, for the price, I'm not sure it was worth it. Great location if you're looking to explore the Arts District or even nearby Little Tokyo, but this apartment is clearly set up by a business more interested in maximizing profit than anything else.
