We will be visiting in the fall and will rent a car. It is my understanding that parking and parking costs can be a problem in Old Town. We would like to stay in a neighbourhood that is close to Old Town and we could walk there and leave the car behind to explore the Upper Town. Our hope is to rent an AirBNB with parking. Would you please provide the names of the neighbourhoods that are the closest to Upper Town? We'll use the car for day trips only.
