I have stayed at the Hotel Rialto previously and enjoyed my stay.
This visit: I'm a very light sleeper, and the first night I noted there was the restaurant fan right underneath my window and mentioned to the front desk that I didn't think I'd be able to sleep with that. The front desk gave me some earplugs. Try as I did, with earplugs, white noise and a pillow over my head I was unable to sleep with that low frequency noise all night (and I had a course all the next day, so tired).
I arranged to be moved the next morning and they did so. A much better and quieter sleep! Very grateful.
This visit I did notice small holes in the sheet and blankets. But otherwise, it was a good stay.
