That's my French press, condensation sets just mere seconds after washing it.
Despite being the summer months, the tap water remained very cold. Not icy cold but I am guessing somewhere around 15 to 20 degrees Celsius.
I asked my local staff about this and they explained that the temperature underground, where the city pipes are laid, is very cold. Something that I have not experience before elsewhere.
Perhaps that explained why the underground subway stations are so cooling....
.... until the people starts filling up the entire place during peak hours.
