Lake Garda is beautiful. The hotel is an average, slightly outdated, limited frills hotel. That being said, it's the norm for what you will get in the area (and at a pretty great price).
If you splurge on a room with a view, it is definitely worth a gorgeous sunset on Garda. The nearest town is about 2km south of the Hotel, so keep that in mind if you anticipate travelling for restaurants or nightlife (BUT it is a gorgeous small Italian town and well worth the 20-30 minute walk or 5 min car ride.
