Cons: it's older so expect that carpets are old, just wear slippers. The bathroom floor wasn't cleaned perfectly. Stray hairs left behind. There are less expensive options.
Pros: LOCATION LOCATION LOCATION!
It's a GREAT location, you can eat a crepe late just feet away and stroll past Notre-Dame and the Louvre in just minutes. Run along the Seine River (just minutes walk) to the Tour Eiffel in a 10k loop. Even a main train station is just a couple metro stops away. Uber to airport 40-50€ Or bus/metro (35 min) if you don't have a lot of luggage. Location is awesome and safe. Even woman traveling alone. Free breakfast, but I left too early to try.
