We had a beautiful holiday in Linfano/Torbole.
Communication with Sebastian is very easy and he is also there if you need any help or tips on some interesting spots.
The flat is absolutely sufficient for your stay with a full equipped bathroom and kitchen.
Highlight is definately the view at the mountains from your balcony.
You need only 5-10 minutes from your flat to Torbole and the beach.
Other places (supermarket, restaurants, boutiques) are also easily to reach by feet.
Malcesine, Lago di Tenno, Riva del Garda and Limone sul Garda are worth a trip to. Also Verona as a "nearer" big city is an absolute recommendation.
So all in all we had a great time there and would definately come back to Sebastian and his appartments.
By the way Sebastian is also offering a sailing trip which is very nice!
