Great apartment! We stayed during Feb and the heat was very much needed and we never felt cold in the apartment. It was a 10 min walk to Naschmarkt and 5 mins from the train station. We-Han was great at communicating with us the directions to the apt from the central station. I would definitely recommend this apartment to anyone looking for a place in Vienna. It's in a perfect location and surrounded by many cafes and restaurants. Thank you for having us!
