We had an enjoyable stay for a week in mid-July. The location is perfect both for a beach vacation and visiting nearby attractions.
We could swim both in Endine lake (K-beach is the best but payable, there are also small free beaches in Spinone) and in Iseo lake (needs some drive, we liked the beaches in Riva di Sol on the west side and "piccolo Tahiti" near the public library of Marone on the east side, both free); water temperature was fine. We visited Bergamo, Brescia and several smaller places (for art lovers Oratoria Suardi in Trescore is a must). Wine tasting in Bredasole farm was another pleasant event. There are many restaurants and shops within short drive distance. The apartment itself is perfect: super-clean, well-equipped. The balcony view is fantastic. Strongly recommended.
