They have better hair dryers at the front desk and the doors/windows have shutters on the outside. I didn't know either of these things until I checked out. (The hair dryer on the wall wouldn't dry a newborn baby's hair.) And my balcony faced the parking lot, lit overnight; in theory, there are shutters, but I can't speak to how effective they are. Surely more effective than the hack system I used for 2 nights :)
Other than that, this is a very decent lower cost option within short walking distance from Bellagio. Of course, be prepared for the steep climb from the city, but when I came in for the first night and took the bus, it was perfect for my needs! And once I visited Villa Melzi, I realized how great the location is.
