Great space, very clean. Great view of the park and the area from the 34th floor. It was a very comfortable space and would have been great for a visit to the Vienna International Center. It is a few minute walk to the metro and a few minute ride to the city center for a generic tourist, but it was also nice to get away from the rest of the tourist crowds. Ewald was a very gracious host, and while I didn't meet him the concierge handled the checkin just fine. There's no mistaking that you're staying in his place, as his personal items are on the walls around you, but it added character. I'd definitely consider staying here again.
