I and my wife had booked two nights at the Bellariva hotel halfway through a roadtrip in Europe, and extended it one more night as we were more than pleased with the location, and standard of the hotel. The view from the hotel balcony is probably the most beautiful we've had, with only a small park between us and Lake Garda.
I saw some reviews of the hotel being renovated in 2017, but to me it seemed as if the hotel was completely new. If there was indeed a hotel with the same name on the same location before, it has surely been completely refurbished - no signs of anything old can be seen.
We ordered a pizza the first night to the room, and it was very good. However, we did not have dinner at the restaurant as it was way too bright for our liking. Our impression of Italian restaurants in general is that they are a little bit too brightly illuminated, making them not so cosy and the restaurant at the Bellariva was extremely bright making us not want to eat there. It was also difficult to find a good illumination in our room, as turning on the bedside lights also meant turning on the ceiling lights making the room rather "cold" at night time.
That being said, I believe the Bellariva is an excellent choice for anyone planning to visit Riva del Garda. The location is great with only a ten to fifteen minutes walk to the town center along the water, and the walk to Torbole is only about 30 minutes.
We will definitely stay at the Bellariva again.
