It's a great apartment, big for two people, very comfortable. Very close to transportation, a central metro station was our neighbor and it was situated at an intersection where a lot of the important line buses pass. The building was safe, with a 24h/24h guard at the door. Brian was very accessible on texts and answered right away every time we had a question.
Negative points: internet in the apartment disconnected often and reconnected afterwards. Also the TV was jolting so we couldn't watch at all.
I want to add something about the neighborhood. We were two young girls who finished university a couple of years ago. We were careful when we walked around during the day and really afraid after sunset. A lot of homeless people, most of them with mental problems, one of them attacked (screamed at) us and we ran away. All downtown is like this except from the streets where they are banned. If you're planning to visit LA, I don't recommend renting/living in downtown for this reason. The building Brian's apartment is is very safe, but not the surroundings.
