I have an 18 and a half hour layover in Vienna on a Saturday night in September, coming in from Istanbul. I arrive in Vienna at 3:55pm and my flight leaves at 10:25am the next morning back home to Virginia. I am wondering, what should I do with my evening there, and I am assuming it is best to get a room at a hotel to sleep before my flight. My preference would be to get a room someplace near the "action", easy access to all the sights so I may drop off my carry on, clean up, then go back out to enjoy whatever I can. Any ideas where the best place to stay would be? Preferably not too expensive! :) Also, I am a 25 y/o girl traveling alone, how safe is it at night in the city? Sorry I am not familiar with this city AT ALL (but would like to be)... any information is genuinly appreciated (Where to stay, anything I must eat while I am there, etc.) Thank you!!
