If you don't have air-con in the apartment, or not in every room, another option is to use a portable electric heater. I purchased a couple of these below for an apartment & €70 will buy you a portable device which heats up quickly and can warm a 15-20m2 room easily enough - bigger versions available. As an example, we'd put one of these in the bedroom around 15m2 for 20 mins before bed, leave on low most of the night and did the job, cheaply - in that apartment no aircon or central heating - so 2 or 3 portable radiators do a decent job.
