Simona was very responsive and a very flexible host. If she's there, and you have booked the single room, you'll share the flat with her. In my case she was gone most of the time which gave me a bit more freedom to move to the kitchenette, which was nice.
Something that was a bit unfortunate, but Simona can't do much: I was woken up by a construction/renovation in the neighbor's room every morning, it was very noisy.
Overall I enjoyed the stay, it was a nice neighborhood, a cosy flat and a friendly host :)
