The queues have become absolutely horrendous and the site is currently undergoing enhancements so there is a lot of dust and debris, and the entrances are convoluted paths.
Once at one of the floors brace yourself for queues just to get back down.
Having said that, it's still definitely worth a visit. The structure is still amazing and the views of Paris are absolutely breathtaking. It is worth getting a guide to have a bit of history and a tour (although not required). Facilities inside the tower are adequate and we'll kept. There is also the perfunctory gift shop and a couple of eateries.
