Nikola was extremely helpful and made us feel very welcome. He even checked up with us halfway through our stay to make sure we were OK and he arranged for his taxi-driver friend to pick us up from the airport, which was lovely. The flat is in an excellent central location with everything on your doorstep. It was not quite as light as in the photos, but this was not so important as it was Vienna that we came to see. It was very quiet and the beds were comfortable.
