Jack’s place is located in a convenient spot. It is about 2.5 blocks from the subway (2 stops away from all the action) or you could just walk there!
I was a little nervous when I first arrived. I’m a single female and try to arrive at my places in the light so I have a better lay of the land - however due to train issues I arrived about 2-2.5 hrs later then I had wanted. I was a bit nervous coming into the building - but Jacks appt is welcoming. Once I got my bearings the next morning I was much more comfortable in the neighbourhood and felt silly for feeling uneasy.
Vienna is a beautiful city and I felt completely safe. It was fun to explore and convenient to pop back to Jacks in the afternoon if I needed something! I would recommend this location. Happy Travels to Vienna!
