Edgar's place is well-equipped with anything you might need for your stay and the location is pretty great (about a 7 minute walk from the RER B and no more than a 30-40 train / metro minute ride to most of the major attractions).
The beds are in lofts which you can see from the pictures. That turned out to be a bit more of a negative factor for my mom and her friend since they tend to have to get up several times a night to use the restroom. For other people, that's probably not as big of an issue. The beds themselves were not very comfortable, but they had fans for all the beds and the living room, which was nice as it was quite warm while we were there.
Overall, a good place for the price, especially if you're traveling with a group of friends and want to be a little closer to the action.
