Bill's place is a great find in DTLA. It's beautiful and well appointed. We stayed there for two weeks for work. We didn't have a car and could easily walk to work, trendy local restaurants, two grocery stores and cool clubs. The apartment has many small touches that only a great host will have thought of, for example, there's extra plug ins by the bed, and the two desk areas are perfect for remote work. The 24 hour security was always available and to a person they were kind and helpful. I did go up to the roof twice to use the hot tub and it was nice.
The natural light coming into the apartment from the large windows is beautiful and you can leave the curtains open all day and in the evening see the lights of downtown turn on.
Downtown LA is a loud downtown, there are a lot of people on the street and you should use the provided ear plugs or some sort of sound machine to block out the city noise. But don't let that deter you from renting this awesome apartment! It's a great find.
