I would highly recommend Catherine's apartment on your stay in Vienna. Located in District 5, 10 minute walking distance to Naschmarkt, outdoor food/restaurant venue. 8 minutes to metro to get to anywhere in Vienna. Her apartment is in a safe area, even at night walking alone as a female felt safe. Her apartment is clean, cozy, adorable.. and there is access to kitchen use and nice bathrooms. She is also very friendly and will give you tips on where to eat, go, shop, etc.
