Is this hotel close to the city centre ie can one walk there or is a taxi required?
Unfortunately, it is too far to walk. Apart from taxis, there is a public transport (bus) to the center. I have no experience with that as we were there by car.
It is some 15-20 minutes by car from the city centre. You have regular bus connections and near bus stop by the hotel. Costs little more tha 1 eur. Otherwise you can certainly take a taxi. Shouldnt be expensive. 6-15 eur or so.
