I would have given 5 stars but I deducted 1 because we could not get the temp to stay at a comfortable 22-24C as there was an issue with the thermostat located in the upstairs unit which seemed to keep trying to bring that unit cooler thereby overcooling ours to about 17C (the vents could not be close off in our unit but we could open the windows on this ground floor unit). If this is remedied for future guests, I'd give it 5 stars!
