We stayed 10 days at Hotel Benacus in late August 2006, driving there in a hire car from Verona airport.
I completely endorse the highly positive comments of your previous contributors about the hotel.
We had a wonderful time. The hotel is situated in a spectacular location on the side of Monte Brione overlooking the attractive small town of Riva del Garda. The rooms were clean and bright. Ours had a balcony overlooking the town, from which we could see the boats on Lake Garda and the mountains surrounding it. The restaurant (excellent evening meals, comprehensive breakfasts, with fantastic views of the town, lake and mountains) and bar was top rate, and the hotel had a lovely patio area overhung by festoons of grapes.
There is a very nice clean swimming pool lying in the hotel's lush, verdant garden accessed by a steep flight of stone steps, which we and our daughter had much fun swimming in, while at other times we lay on the sun loungers around the pool soaking in the sun.
The manager Marco is a great guy and all the staff without exception were extremely pleasant and helpful.
The hotel attracts a mainly German-speaking clientele (as does the Riva area - it was after all not long ago a German-speaking part of the Austro-Hungarian empire). Virtually all the staff however are trilingual, speaking Italian, German and English.
The hotel is very peaceful. This is in contrast to Riva itself which was a revelation. I hadn't realised before I arrived that Riva and neighbouring Torbole were renowned activity sports centres, noted for windsurfing, mountain biking and so on. We walked along the lake-front at Riva and Torbole and have never seen so many (mainly young) people engaged in jogging, cycling and other sporting activities. As sporting types ourselves this was a pleasant, invigorating surprise.
But less sporty types are also catered for in Riva. The old town, towered over by a mountain, has many attractive buildings, with good restaurants and designer shops. It's very lively day and night.
Riva also provides a good base to go and explore the wonderful surroundings: the lake itself, the mountains (the pre-Alps) and villages. There's lots to do, though I think a car is essential to get around and see the sights (There is a small car park beside the hotel where we parked our car).
We would very willingly go back to Hotel Benacus.
