My stay in her place was amazing. It was nothing short of excellent in all areas. The facilities are all brand new, and kitchen is very modern. My mother cooked a lot of foods in the kitchen, and she said "This kitchen is perfect." Everything was so clean and well organized. The location itself was better than I could have imagined. The place is an ideal neighborhood to explore real Vienna. Within a short walk, there are a lot of small stores and restaurants. (Plus, there is a great bakery around the house as well. You should go there for sure.) It's very convenient to public transportation as well. But, only one thing I should write down here is that there is no elevator in her place. I needed to carry my big luggage to 3rd floor. It was a bit tough, but it is kinda acceptable...
By far, Christiana is very kind and helpful host. I could not see her in person because she went to a different place for vacation, but she helped me via message. She tries to make a warm and comfortable environment for us. I am very happy to stay at her place. My mother and I had very precious time there. I highly recommend you this place.
In the end, thanks Christiana!
