Maria is very quick in responding to all of my messages and was so kind to answer all of my concerns. I did not meet Maria outside but her friend Vasu is the greatest roomate. My friend was sick on the last day of the stay due to weather shock and Vasu was so nice to give me some rice so i can cook some porride for my friend in the very of the morning. The house is super clean, the room is well-decored with a map of all sight-seeings, and the bathroom is spacious which is very comfortable. The place is only 15 mins away to some famous tourist attractions in Vienna, and close to Vienna central station, easy to travel intercity as well.
