Fiorenzo was very helpful and the apartment was very nice. We communicated by Whatsapp and he came to the main road to guide us to the apartment house as it was not easy to find (my navigation system could not find it). Beautiful view from the balcony on the lake. We did get linen and towels which were also changed once (as we stayed 10 days). We did get coffee, milk, juice, water, cookies and brioches for free :-) and even a bottle of sparkling wine as a welcome gift.
We can absolutely recommend this apartment!
It is 15 minutes by bike (5 minutes by car) from Sarnico, 10 minutes from the public beach. But you need to climb up the hill on the way back (quite steep).
