The room's super small, which would be totally fine as we only were there for about 9hrs daily (sleeping and getting ready). The huge problem was the super tiny bathroom. NO ventilation. You have to sit slanted on the toilet because it is right against two walls. The shower is so small that water gets everywhere. Forget about body wash, shampoo, conditioner. All they provide is a little square packet that says for body and hair, but the packet doesn't hold enough liquid to cover both, even if that doesn't bother you. It bothered me. I ended up buying my own bath products. Second major issue is the bed is like sleeping on a plank of wood. Way too firm! No give. Uncomfortable.
Pros: staff was good, room was always clean, felt safe, and walkable (restaurants, metro, Eiffel Tower).
