This is the place to stay if you want to have the large fresh fruit and vegetable market very very close. And it is just two stops to the opera. And the Theater an der Wien is in walking distance - treat yourself to a night or two there when you watch some opera performance. You will love it. Prosecco for breakfast! :)

Have stayed there twice because the location is just superb. Close to Naschmarkt and walking distance to Kärntner Strasse, Graben and the inner city.
But the Drei Kornen just doesn't deliver value for money. Last time we got a room two floors above where the elevator runs to, just under the roof with sloping walls and poor maintenance. Breakfast isn't really great eighter. To be fair, the guys at the reception is nice and helpful. But it doesn't change the fact that you can do a lot better at a lower price in the same neighborhood

The hotel is located across from the Naschtmart, and a nice walk to the City center. Metro station was a few meteres away. The hotel room was good, no fancy furniture, but comfortable. THe only problem we had is that we stayed in a room for 4 people, with closet space for 2. Breakfast buffet was nice, and when we had a special request for our children they were more than happy to help.
All in all this is not a fancy hotel, but it does have a great staff.

This was our main hotel for our stay in Vienna and we were very happy with the easy access to the Naschmarkt. If you are not much of a walker, this might be a little far from the Innere Stadt but consider that there are several restaurants on the same block and the Naschmarkt has grocers and cafes/restaurants across the street.

In our case, a corner room with a bay window looking down Schleifmuhlgasse and high ceilings made for a spacious feel. Free Wi-Fi.

We paid €100/night, which I considered a good value but pre-payment requirement rather than just a reservation is in my opinion not a customer-friendly business practice. I understand the risk to the hotel's revenues if people cancel but it would have been nice to have more flexibility to change our plans.
