The place was really cool and unique, and in a fantastic location. It was the perfect choice for coworkers staying there for a conference with plenty of room, and not hot at all inside despite the heatwave happening in Paris at the time.
However there were not enough linens for the amount of rooms advertised, and some guests had to sleep under towels despite multiple requests to provide linens. There was also only 1 key for 6 people, which made it very difficult to get in and out safely. Also be aware that there is only one bathroom for a large amount of bedrooms, which was not a problem for us but could be for some people.
There are also few real doors, so sound carries throughout the whole house and there is little privacy. This also wasn't an issue for us, but something to look out for.
Overall, the stay was fantastic and perfect for what we needed other than the linens and key issue. I hope this is able to be fixed for future guests.
