We did our tour reservation with Viator through Tripadvisor and we had a great local guide all set up before we left home.

As far as I've noticed,you can drive in the city, but the old town is to walk through. And there is no place to park in front of the hotel. I can't help you with more information, cause I'ven't get the city driving, but I must say that I felt that you can park not far from the hotel.

The hotel has a couple of garages they charge for quite swiftly; apart from that you can use public parking for a couple of Euros per 24 hours, they are safe and at the same 5 minutes walk from the hotel as the garage.

There is no solution for parking at the hotel premises, as it is located in the city's central square. However, there is a paid parking 250m away on the same street, you will see a barrier there. The parking place costs an equivalent of 0.75 eur/hr and you don't get any discount when parking for several days/nights. Then you have another parking place 30m further down the street which is free. During the day, especially in the weekends, it's difficult to find an empty place there but during the late evenings that becomes possible. I left my car there for the night, with no problem.
