Thank you very much for your kind guide to the Vienna travel information and for your prompt reply to the questions.The accommodation was clean and cute. It takes about 12 to 3 minutes to pull the carrier from the central station in Vienna. It takes about 10 minutes to walk to the Palace of Belvedere. There is no air conditioner in the accommodation, but there is a fan. Even without air conditioning, it's not hot at all at night. I liked the key except I was embarrassed because I wasn't used to it. Thank you~
