A landmark of LA, nice stay, bad valet
Went for a bday weekend. The Bonaventure is a signature place in LA worth visiting for its massive interior, glass elevators and central location. As a Westin, you get the usual amenities. We were very pleased when they changed our rooms since the first room, a double bed, was too small for us to sleep comfortably. The rooms were small but plenty enough for our needs. Nice view of the city. Easy walk to the LA library, Pershing Square and Perch restaurant/bar. We slept well at night being on a higher floor away from the street noise. 
Now, here's my beef with an upscale hotel such as Westin: their valet was horrible! It took us nearly an hour to get our car on the day of checkout (Sunday). The day that everyone is leaving, they have no clear, organized system of getting your car. At first we were told 20 minutes, which after 40 minutes we had to inquire, till finally they retrieved our car. Unfortunately there is no reason why some people waited longer than others. There were literally people squatted along the hallway waiting for their cars in addition to all of us waiting in the valet location. For the price you pay for valet, they need a better system.
