I had a great week staying at David's studio! The location is very convenient, especially for easy access to the Prater park (a great place to start the day with a run or walk!), and the U-Bahn station is a short and easy walk away. And a nice Billa (the grocery store) is also extremely close. The building is new and everything is clean and nice. Laundry was easy and inexpensive. The balcony made every breakfast something special and I hosted friends for drinks with a view on the rooftop terrace. The apartment had all the conveniences I needed (dishes, a fan, even extra shampoo). It was easy to communicate with David. I will stay here again on future Vienna trips and I'd recommend it to anyone! :)
