I wouldn't bother, having done so once to my immense frustration. The roads there are horribly confusing, and the available maps absolutely do not help. My friend and I actually had to pay a cabbie to drive in front of us to get us through the hideous one-way system near our hotel. All sorts of twists and turns and almost invisible signposting. And when it rains, it rains in such torrents that you simply can't see to drive, especially on the hair-pin bends. And there are heaps of hair-pin bends.
And look out for thieves. We were robbed in the hotel by thieves who must have brought a ladder with them, since we left our balcony door a few inches ajar over a considerable drop, thinking we were safe. We weren't.
