I spent 2001/2 working in Trento (same latitude as the top of Lake Garda) and gliding occasionally from the airstrip there. Brescia is at the foot of the valley, where it runs into the plain of the Po valley - I'd guess about 100km away - and there's a continual stream of traffic arriving from Germany and Austria.
Facilities seemed to be good, and the atmosphere was friendly and welcoming. ATC is in both Italian and English - which can be heavily accented, depending upon who's in the tower, but visitors seem to have no problem. The airstrip has Avgas and jet fuel, together with a good hotel/restaurant and the delightful Caproni air museum all as part of the same complex. In addition to the stream of visitors, there's a helicopter school, a handful of light aircraft and the gliding club (aerotow only). There are also the local rescue choppers, which will be given priority. It generally seemed a well organized and disciplined operation.
Security has tightened over the last three years, and I understand that visiting aircraft have to chat to the local police about their documents upon arrival. This is, of course, a routine event for them - it'll probably happen a dozen times on a sunny weekend afternoon - but they may have to pop out from the nearest police station, giving you just about time for a coffee in the hotel bar.
The Jeppessen charts used to indicate a swathe of controlled lower (and higher) level airspace over the region. Nobody I spoke to could understand this: the airspace was regarded as uncontrolled. Nearby airfields are Bolzano (up the valley) and Verona and Brescia to the south, with controlled airspace only in the latter region.
Let me know if you decide to go this route, and I'll dig out some contact details for the folk down there - the gliding CFI is the airport manager. The tower folk are very friendly, especially if you can talk about Formula One! And the museum is well worth a visit.
