I needed some service work done on a macbook and didn't want to deal with the Louvre so I thought…read morethat I would check out the Opéra store.
The building is magnificent, not the usual glass, white-walled Apple store, but a restoration of a beautiful old bank. Complete with spiral staircases, marble and tile floors, wrought-iron railings, and a huge skylight, the store itself is a work of art. The display space for iphones, ipads, and computers is big enough to be accessible even with the huge crowds this store can draw.
I had made a Genius Bar reservation online so I didn't have to wait but I would not advise just showing up and hoping to be served as the store was packed on both visits. The Genius Bar tech was incredibly friendly and competent. The other techs that I saw were incredibly patient given the questions that people were asking them. The Macbook was under European consumer warranty even if no longer covered by Applecare but the tech said they could still provide the 400€ motherboard replacement for free (instead of having to pass through Darty where it was purchased).
All said, another fantastic Apple support experience by a courteous, competent and efficient staff.
