Me and my best friend stayed at Lise's home for three nights. We were their first guests and everything worked smoothly and Lise and her husband were super nice, helpful and gave us a lot of tips. The apartment itself is quite big, apart from the super tiny bathroom. It was the smallest I've ever been to, but had everything we needed, so that's not really a problem. The only negative thing I could say is that the lighting in the whole apartment was super soft and not really good for reading or stuff. But apart from that - let's be honest: the flat was super clean with nice and minimalistic design and a lot of free space, had a double bed and a sofa you can sleep on, a nice little kitchen, a great location (next to a metro station) and we didn't really miss a thing.
PS.: the apartment is in the fourth floor without a lift, so if you have a big suitcase, keep that in mind ;)
