As mentioned by others, location is everything! You could not find a better spot for touring museums, taking metros, or shopping.
The photos are accurate … the place is one large room that divides into 2 separate sleeping areas by sliding partitions. That leaves the living room/sofabed as a third area. The beds are very comfy and the linens are nice, but the sofabed would be difficult for two adults to sleep in.
Make sure you try the bakery on the left right before the church … great pastries starting in the morning and sandwiches and salads added late morning. In the afternoon they also have some mains (chicken in a mushroom cream and chicken tangine) you can take to the apartment if you’re too tired to go out to dinner. Bread is also wonderful!
