We stayed within the walls in the historical centre and enjoyed that.

We rented an apartment - not in the fanciest neighbourhood but the walled city is so small that it was not a problem. We enjoyed having all the facilities right there and we enjoyed being able to walk home after dinner. http://tinyurl.com/2mnuw

You don't say when you are going. If it were in the hottest weather, it might be preferable to stay in the countryside nearby.
