This is a very nice apartment and location in the heart of Vienna's commercial district. The apartment is very conveniently located within less than 5 minutes walk to the Nubagasse subway station that takes you all over the city. It is also above a supermarket which was convenient but I arrived there on a Sunday where everything in Vienna is closed. If you plan to arrive on a Sunday, make sure you have provisions. Otherwise, there is a small supermarket (U3 supermarket) at the Westbahnhof subway station that is open on Sundays and late at night.
The apartment was sparkling clean and had all the amenities I need and was just as in the pictures provided. Ella was very responsive to all my communications before and during my stay. I would definitely recommend that place.
