Riverside is tremendous and I strongly recommend it. When factoring in price, I think it's the best resort at Disney. Sure, a hotel like the Boardwalk Inn is better overall, but it also usually costs at least twice as much per night (and often more).
It's much quieter than almost ever other Disney resort, it has a food court and a table service restaurant. It also has pretty easy access to the French Quarter's food court, which is better (at least for breakfast), depending on where you are located at Riverside. The boat to Disney Springs is a pretty relaxing ride as well.
I like to stay in the Royal Guest Rooms, which are a bit more expensive, but have the best location (I don't care about the theming). There's a bus stop a short walk away, plus the main lobby bus stop isn't much farther (which means if you're ready to get off the bus, you can just get off at that stop without having a long walk back to the room instead of waiting for it to complete the circle). You can also get to the food court etc. in a short walk, and you can walk to the French Quarter in a relatively short walk as well.
There's also a bar with a piano player for evening entertainment. I've never eaten at the table service restaurant, so I don't have an opinion on that, and I don't think the food court is great (although that's true of most resorts), but I prefer going to Disney Springs or to other specific restaurants to eat anyways so that's not a big concern for me.
