The apartment is very nice and comfortable. The position is great, very close to the U-train and to the Old-Danube. Perfect for the Conference Center but good also to visit the city. The building is on a very noisy road but the doors and windows keep the noise Completely outside, unfortunately the balcony is uncomfortable because of the noise. Check-in and check-out easy. Biljana was nice and communication easy. We will certainly be back at the next conference!
