I didn't meet Christina but her roommate Eve. She was very nice but we saw her just the day we arrived. I'd have preferred more communication between us and her and socialize a little bit more but she was always closed in her room, I think it depends on the different cultures we are from! The house is very central in a wonderful place of Vienna, 5 minutes walking from the nearest underground, all surrounded by cafes, shops and restaurants. It was quite clean as the room, but there weren't any curtains so in the mornings we were woke up by the sunlight and we couldn't sleep till late :( I liked stay there for the position and the freedom in the house, I felt as I was at my house. The only problem was that the house is on the 5th floor and there isn't lift!
