Rainer's apartment is a wonderful place to stay in Vienna. It's clean, comfortable, stylish and well equipped with everything one could wish for. The location is great, there's a nice square with trees, benches and a beautiful old church right in front of the building. Shops, restaurants, bars and nightlife are within easy walking distance and even though there are many options for public transport, you'll rarely need to make use of them. Another big plus are Rainer's awesome recommendations for things to do in Vienna, there's a book in the apartment that keeps track of them. So if you're looking for a nice, centrally located place to stay, you found it :)
