Simplicity is key and this hotel did it perfectly. It was exactly what I needed for a solo 3 nights in Paris, ensuite, comfy bed, lots of space and in a nice, quiet area of Paris where I felt safe to walk around by myself and was easy access to the metro.
My only con is that there was no inside lock/door guard/chain on the door and keys had to be handed in on leaving the hotel, making me feel slightly uneasy that someone could go into my room. I ended up propping a chair against the door whilst I was in the room for extra comfort.
