Cheap, convenient, boiling

This is student accomodation but that is of pretty good standard these days with good en-suite and kitchenette in this instance. All good, mostly clean and good shower, comfortable bed. There is only a blind, no curtains, but the main problem was it was boiling. Now, it was a really warm day but the blind had not been shut or the window left open so the room was boiling on arrival, and due to the very small window did not cool down at all. My advice in future to the staff would be to draw the blind and open the window in advance.
