My mum and I stayed at Line's apartment for three days while travelling through Europe. Check-in and communication was easy, and the apartment was spotless – exactly how it looks in the photos. The area is fantastic - super buzzy with great restaurants around the corner (go to Mirabelle for great breakfasts and Baest for delicious pizza). Only downsides were the heaters not working in the bedrooms, and the single bed in the second (children's) room being fairly uncomfortable to sleep on. And yes - be aware of the stairs before you book! I was fine but my mum struggled a bit. Worth it though. Would recommend.
