I stayed with Claudius and Amanda at the end of a business trip. The room was very clean and I appreciated the extra fan in the room as the area around Downtown gets very hot.
It was a good base to go to the Staples Centre and explore downtown. Pico Union is a great little area to explore especially as you walk to McArthur Park for the Metro or Pico Station on the other side. At night the walk back from Downtown was a little ropey, so definitely consider a taxi if it's late.
I'd also recommend walking round to the main street and checking out the Guatemalan cafe just a five minutes walk away. You can get 3 pastries for $1.
