The Chess Hotel in Paris

Brilliant location but I paid for a deluxe double room and it was really small. No view out of window (looked out to a concrete wall) and the room was very dark.

Stayed at the Chess Hotel between 13.10 -15.10, on the sixth floor, room 610.
I have chosen this hotel, based on the Trip Advisor reviews, mentioning that it was quiet, as I had bad surprises with three hotels, in the same area before.
I chose to have a room facing the inner court, and not the small street below, because sleep is important to me.
The first night was fine, because there was no one in room 611, and I had a good night rest.
Unfortunately, the second night it became obvious that the soundproofing is not good enough, because, with guests in the adjacent room, i.e. 611, I had one of the worst night rests in my life. Reception was called, they came 5-10 minutes after, when the guests in the other room stopped making noise, i.e. laughing, so the Reception concluded that there is no noise.
I am still hopeful that at some point in the future, instead of noisy hotel rooms, as tourists or when on business trips, people will sleep in sensory deprivation tanks, fully soundproofed, so that they can get a good night rest.
