We enjoyed several nights in this apartment. The patio is a little tough to describe! It's waterfront, as in you are ON the water, and you get to see the kinds of views that are in the magazine. One afternoon when the cruise ship was in, I heard the boat tour operator say, "If you're either extremely rich or extremely lucky, you can live here!"
I recommend bringing a tripod if you are a photographer. The evening lights are beautiful.
We walked along the pier the first night to get our bearings and found a little shop where we could buy enough food for breakfast and snacks. There are restaurants along the water for dinner. The water taxi to Valetta is at the end of the harbor and we preferred that over the ferry.
We did not rent a car.
