The place is amazing, and the best value place we found in Paris. By far.
It's extremely spacious, it's nice, its located at a great place. it's really cold.
It is a tad cold, so hopefully it's not too cold outside.
Checkin is a bit hard, because the code on the door is tempermental, if it starts yelling at you. don't be that worried. 10 minutes later it would relax.
Also, not that its a problem but heads up, you are dealing with a company, not a person. We never met a Gary, and when we had an issue, we had to go through a phone line, click a few buttons to get support and then get support by a person who has never been at the apartment and wasn't very helpful. So manage your expectations for communication and be patient. They mean well but.
Again though, the place is epic. really really good.
