Overall, I liked the Hyatt Regency Paris - for the price, it's quite frankly an amazing value. The location is not a huge turn-off as it's walkable to the Arc de Triomphe, and the Metro is relatively easy to use. Here are my pros, cons, and photos:

Pros:

• Upgraded from a base room to a "Deluxe" Eiffel Tower View on the 29th floor - I am not sure if suites were available or not, but I wouldn't be super excited about a suite that is just two connecting rooms anyway
• The bed is quite comfortable - plush covers (rare for a HR), plush pillows, decently medium / plush mattress (though, I think it was two connected to each other) - no issues sleeping in this bed for two nights
• Shower pressure is good
• Design felt compact but efficient with plenty of ledges, etc for storage
• The lounger couch was useful and comfortable
• Tasty bar of chocolate waiting in room as a welcome gift (along with wine, which I don't drink)
• I appreciated the quality of Housekeeping - she dropped a pillow accidentally and made sure to get a replacement pillow case
• The lounge was nice - good coffees and hot chocolates, real desserts at tea time (the desserts at tea time were better than those at evening service)
• Breakfast in the lounge + Skybar was good - good scrambled eggs, good bacon (if you don't look at the color), good croissants - pancakes and waffles could be improved
• I didn't have an issue with wait times due to the destination dispatch elevators, but you could tell they confused some people

Cons:

• For some reason, I was auto checked out around 10:30 AM (CC charged, app said checked out, and folio emailed) and folks were knocking at 11 AM - I had forgotten to ask about late checkout, but 10:30 still seems a bit early - I called down and told them I would leave around 1 (they seemed to think I had asked for an early checkout, which doesn't make sense)

I would have no issue returning here to extract value out of nights in Paris.
