We really enjoyed our stay! We had two couples so 4 people total. The loft is a loft so be aware if you need/want privacy and you have more than 2 people.
The only thing to be aware of is if you are over 6'1 you will not be able to stand upright in the loft because of the low ceiling. I just ducked a bit the whole time. No real complaint here, just want others to be aware.
The location is really great, accessible to metro, tons of walking and an awesome wine shop and bakery 2 blocks away.
Would recommended to anyone looking for a great place to stay in Paris! The check in and our where so easy, and the communication from start to finish was almost instant! We even had a member of our group forget a water bottle and they are making sure they send it over to her. Great stay and staff don't pass this one up!
