Dropbox
A fun intern perk at Dropbox is Parents' Weekend, during which the company flies interns' families to its San Francisco office, provides housing for everyone, and organizes a series of talks to explain Dropbox, its mission, and what the interns have been doing.
Fun gatherings aside, Dropbox provides interns with free housing in two-bedroom or one-bedroom apartments, shuttles to and from the office, music room with a grand piano and drumset, massages, haircuts, gym access, an in-house restaurant, and coverage for expenses such as phone plan and public transportation. Interns can experience Hack Week, during which the entire company halts their normal activities to work on anything they want.
Oh, and interns can set their Dropbox space quota for life.
