Me and my parents stayed in Gerald's apt for 2 nights. It coudn't have been better. Even though we booked the apt in last minutes, he managed to welcome us and it was perfectly prepared. Apt was was big enough for three of us and very neat and clean. It lookes better than it looks like in the pictures. We found everything we need and very comfortable to stay. If i have chance to come back to vienne i will defineatly stay his house again!
