What we really liked about Christine's place was the location and comfort of the home. It is close to many good restaurants. Tata, a Vietnamese place right down the street is delicious we ate there twice and Mughulhof, Indian food 15 minute walk was excellent. The tram is a 2 minute walk and the subway train is 10-15 minute walk. The house has everything you need to cook and the market is just down the street, it closes at 8.
Christine is delightful, very easy to communicate with and welcomed us with champagne and beer. If you are looking for a fancy place with a modern look this isn't the place for you but if you want to come back to a space that feels like home where you can relax and have a glass of wine while sitting in the sunroom or on the patio and enjoy some music you will enjoy Christine's flat.
We rented bikes one day at Reanimated Bikes just around the corner and had a great day riding the Danube Canal stopping to watch the sunset while sipping a cocktail. This is a great break from typical sight seeing and Vienna is super bike friendly with many designated bike paths.
The only thing we would change is the bed, it was fine but would have been more comfortable with a thicker mattress. Just FYI the bed is a true loft bed so stairs are involved!
We would definitely stay here again.
