Sparkling clean, kind host, and good location.
The upsides are that it is really close to some awesome restaurants, Little Tokyo, and the LA Convention Center. The apartment is in the basement and the building has a doorman who buzzes you in, so you definitely feel safe, claustrophobic hallways leading up to it notwithstanding. Elissa stayed in the apartment with us, but she was never intrusive or loud--it was sometimes hard to tell she was home at all, really.
The only major downside is that the guest bed is an Ikea pullout couch--not very comfortable for more than one night. I was kind of in pain by the third night. Also, there were no signs or directions in the building to lead to the laundry or pool area, but that's not Elissa's fault.
