Well, there is a heating system, but it’s shared throughout the entire apartment building, so we have no control over it whatsoever. Naturally, the temp is set so that the people on the first 2 floors are comfortable, so that means that everyone above (we’re on the 5th of 10 floors) suffocates during the winter! If we kept the windows closed, it would easily top 30 deg C in here! So we basically leave the windows open year-round. During the summer, the heating is off (thankfully!) but it still gets hot, so we have a series of fans throughout the apartment which get the air flowing and it’s mildly bearable.
We will have control of the heating in our next apartment in Montreal (one more month…whee!) and we will likely keep it relatively cool, even in the winter. Saves money, and it’s just the way we like it. No A/C, though, so it remains to be seen how hot it will get during the summer. The windows at the back are shaded all day by trees, and there is a small tree in front of the front windows, so that should help, but the living room faces the west.
Either way, it will be better than here!
