I am staying in Hidden Hotel now, and thought I would knock out a review before I leave.
Very friendly staff, spoke great english and didn't make me feel guilty for not speaking French. I wish I was able to speak French, as it is a truly beautiful language.
Staying in the "Emotion" room. The room is of adequate size, has nice decorations, and a fantastic shower!! Great water pressure to rinse yourself after a long day touring Paris.
The hotel is close to Arc De Triomphe, which is nice for us who are relying on taxis, buses, bikes, etc. The only downside for me is the bed sheets, I feel like I am sleeping on canvas.The bed itself is comfy though.
Overall, fantastic hotel.
