My husband and I stayed here for 3 nights in a 'cute' suite and it was the perfect place to stay in Vienna.
The apartments included small touches that really made a difference - free & fast internet, nice toilettries, helpful information booklet with lots of local restaurant/cafe suggestions etc, an espresso coffee machine.....
The kitchenette had a stove and microwave, and sufficient pots and pans to cook a meal (thought no oven unfortunately...I think the larger apartments would have one though).
The location is right in the centre of the city, close to lots of main attractions and with lots of restaurants close by. There's also a supermarket across the street to get groceries without having to carry bags across the city.
Most impressive of all was the service here - we arrived early (12noon) and the apartment was cleaned for us within 15 minutes without any trouble, restaurant bookings were made happily, and the staff were always friendly and easy to talk to with no request too difficult (excellent English helped too!)
We were also able to secure a cheaper rate for the three nights by paying on booking instead of departure - a saving of around 50 Euro! Well worth asking if you're certain which dates you intend to stay.
Overall, we would highly recommend this place for a stay in Vienna!!More
