We (couple, mid twenties) spent 4 nights in Annalisa's apartment and we enjoyed it very much! Unexpectedly but very conveniently Annalisa could welcome us at the apartment earlier than the check-in time. She showed us around the apartment and gave us some tips on where to eat and where to go in the area in good English (and she speaks even better German). The apartment feels like a proper home, including decorations, and is very comfortable (with air-conditioning, fast wifi, a four-person dining table, ...) We also made good use of the kitchen which is suitably equipped for preparing simple meals (with a spacious stove and a small assortment of pans, though kitchen knives were lacking at the time of writing).
The location of the apartment is ideal, lying only a few minutes walking from the train station and about 10-15 minutes walking from the historical city center (during which you'll pass through the modern shopping district).
All in all we would heartily recommend staying in Annalisa's place, and we would like to thank Annalisa for hosting us!
