We had a pleasant stay at Claudia's. The checkin and chekout procedure is made easy and Claudia was available on the phone and able to communicate in English as I don't speak Italian at all. The place was clean and comfortable and located 5min from the Centrale train station. As advertised, there is a club downstairs that plays electronic music all night long which can be bothersome for sleeping, although it was ok for us with some earplugs.
I would probably go there if I were to return to Milano.
