If you’re going to rent a car in Estonia be sure to pick it up when leaving Tallinn or drop it off when you arrive in the city. The Old Town is an entire tow-away zone, which is strictly enforced. Designated car parks can be as much as £2.50 per hour, while on the outskirts of the Old Town it’s around £15-20 per day and further away it’s apparently free. Otherwise make parking a consideration when booking your accommodation.
