The best parts of Adrian's place is the perfect location and beautiful view. We were welcomed with a lovely welcome basket, which was a thoughtful touch. Another pleasant surprise was a small a/c unit that kept things relatively cool on hot days (although it lets off a lot of heat). If you are a coffee person, there is an espresso machine and other equipment.
As others have noted, the bathroom is on the small side (I think the shower stall is only a couple square feet). I'm average size and made it work -- it might be tough if you are larger or claustrophobic. I ran into a couple minor issues like the wifi not working and finding various hair on the linens. Overall, it was a good stay and the location doesn't get better if you want to stay in Marais!
