When I asked Violetta if I could stay with her, she replied within half an hour so it took no time to find an accommodation.
She doesn´t live directly in the city center but there is a bus stop around the corner and if you like to walk you can be at her place within an hour walking from the Waverly train station through the city and seeing the neighboorhood.
She had little notes in her flat so I could find my way around even when she wasn´t there which was very nice and useful.
I only saw her in the evening because she was working and stood up earlier than me but she is a really nice person and I enjoyed my stay!
