What is comfortable in room temperature is one of those issues that appears to vary widely between where you live and what you have used to.
When I was in Venice earlier this month to check out the latest Biennale, I came across the following notice at a hotel where I was staying, which wasn’t an issue this time, since it was fall.

The Notice in Text Format:
CITTA’ DI VENEZIA
AIR CONDITIONING NOTICE
Dear Guests,
Venice is a fragile city and a unique cultural heritage site, where every responsible choice helps protect its delicate urban, environmental and historical ecosystem.
For this reason, in accordance with Italian energy-saving regulations, specifically D.P.R. 16 April 2013, No. 74, and with the provisions applied by the City of Venice, climate control must be used with care and responsibility.
The indoor temperature of cooled rooms must not be lower than 26°C, with a permitted tolerance of -2°C.
To support energy saving, reduce unnecessary dispersion and help preserve the delicate balance of Venice’s environment, the windows will remain closed.
This also helps avoid unexpected visits from some of Venice’s tiny local guests — including insects and our charming, but rather persistent, mosquitoes.
Thank you for your cooperation
26 Celsius, for those who still use the imperial measurement system, is 79 Fahrenheit.
However, there is a permitted “tolerance” of 2 Celsius, so the lowest allowed is 24 Celsius, or 75 Fahrenheit.
Conclusion
I tend to go to Venice once a year/every other year, usually before (spring) or after the high season (early fall), to coincide with the Biennale, when the temperature is usually quite comfortable and the evenings cool (and the worst crowds are gone).
My issue is that if it is cold, I can always put on more clothes, but when it is too hot, there is only so much you can remove (this also applies to in-flight cabin temperature). I cannot sleep comfortably if the temperature is too high.
But air conditioning is out of control in some places, like in the US and the Gulf.
Even when it is 40 Celsius outside, the inside temperature is sometimes so low that I have to put on a sweatshirt and even go outside for a few minutes to warm up (unfortunately, not a joke).
