We stayed here two weeks at the end of April and the weather had certainly turned to the colder. Heating in the apartment is by two wall-mounted heating/ac units (one on each floor). The downstairs heater is in the bedroom and is not sufficient to warm the entire ground level (i.e. entrance hallway, laundry room, bathroom). Comfort on the second level is much easier to achieve. All this is to say you'll be spending the bulk of your waking hours upstairs if you are here in the colder months.

That out of the way, I must add that we found Katrina to be genuine and extremely generous towards her guests (us!) Foodies and shop-browsers will love this location. As a family we enjoyed Princes Park, the Carlton library, and were even pleasantly surprised by a calming stroll through the Carlton cemetery (don't knock it 'til you try it).
