First time in Vienna, and what a great place to see it from. Dan's apartment is exactly as it looks in the pictures and the place is fantastic. Spotlessly clean, stylishly decorated and everything you need, with the big plus that Dan is a superb host - great communication, lovely little touches around the apartment, chocolates, fizz and nice things everywhere. Really felt like a home from home, to the point where we had a few hours in with Netflix and a bottle :)
Location wise, you can be in the centre of town in fifteen minutes, and at the airport in 50. I would recommend this place to anyone. First class.
