Our week in Vienna at Gregor's place was great. Communication with Gregor was easy and prompt. Check-in was smooth. The apartment is in a lovely area with lots of restaurants, markets, shops, and close transportation connections. Many sights are within easy walking distance. The view of the Rathaus tower and St. Stephens in the background from the living room make those flights up worth every step. The bed is so comfy. We really enjoyed coming home to Gregor's apartment after a full day of sightseeing.
