I stayed in Roberta's wonderful apartment for 5 nights and it was a great experience.
Roberta was away during my stay, but I was welcomed by her husband which was extremely nice. The apartment looks even better then the photos, fully renovated with a roof terrace looking over the city.One of the best things for me was the bicycle which I widely used to explore the city. The neighborhood was lovely, with everything you need in a short walking distance and felt very safe for me as a single traveler.
So, I would definitely recommend Roberta's place!
