Really big (really big!) apartment in a block with maybe 5 other flats, with fantastic views of Lake Iseo. Extremely clean, with lots of equipment/utensils etc. Excellent value.
It's up a very steep hill from the town - and quite far - so a car is very handy (essential?) if you want to go out for food/drinks etc.. or to catch boats on the lake.
(+ a really well equipped gym room, if you want to exercise on your trip!)
