Silvia's place is great. The garden is a real asset, and the view of the park is lovely. The apartment is a nice walking distance into the city, perhaps 20 minutes, but there are lots of interesting places and squares nearer than the city centre. If you are there in summer and it is hot, there is a nice outdoor pool at Sterlino, about 15 minutes away by taxi, I'd recommend that as a nice break from the heat. Bologna is a great city, lots to do and see, but a very genuine place too.
