Harry was helpful and answered very fast to the questions we had before arriving in Vienna. The apartment has a very good location, it is clean and cosy. The best: enough space, fast wifi connection, coffee machine (not Nespresso but Cafissimo, also good cofee and you can buy the capsules in the supermarket). Supermarket in downstairs and metro just 2 minutes walk. You can also walk in 5 min to the Belvedere museum/palace and the city center, though we did it with metro and trams as they are very easy and fast. The restaurant in front of the apt. is good and with atmosphere, nice Austrian food for good prices and big portions. We also liked the big TV screen and the sofa after the whole day walking in Vienna!! :)
