Gri’s place was perfect for my family of 5’s weekend trip to Vienna. Apartment is a half mile walk from opera house, tenth of a mile from subway station, about a mile from the CAT and 200ft walk to a large strip with markets, restaurant, bars, etc. we were easily able to see the center from this very convenient location. We also felt very safe walking through the area late at night. Accommodations were as advertised, no complaints. Highly recommend to anyone.
