The field runs a control tower inside Class D airspace, and the whole of it sits beneath the Class B shelf that wraps Los Angeles International. From your first taxi call you are talking to a controller, reading back a clearance, and holding an altitude because the shelf is above you. A student who learns at an untowered strip has to add all of that afterwards, usually in a hurry and usually a fortnight before a checkride.
The honest cost is that your first two or three hours are busier than they would be somewhere quiet. Some people find that overwhelming, and we would rather say so on this page than discover it with you at hour four. What happens next is that it stops being overwhelming, permanently, and you never have to learn it again.
The field elevation is 802 ft above mean sea level. On a hot September afternoon the density altitude runs to roughly 4,100 ft and the aeroplane climbs like it. Computing that and planning around it is exactly what 14 CFR 91.103 asks of a pilot in command, and doing it every summer for a year builds a habit that a sea-level student has to acquire later.
West of the field the Santa Monica Mountains and the western Valley give you a practice area with room in it. East, the Burbank hills and Hollywood Burbank’s Class C sit close enough that airspace boundaries are a real thing rather than a diagram in a book. Both are a short flight from the runway.
