I really enjoyed my stay at this apartment. It is very clean and spacious, with a comfortable bed. The kitchen is well equipped with cooking utensils and Alexander kindly invited me to help myself to any foodstuffs. Check in and out were both very smooth. I didn't meet Alexander but he responded quickly to any queries and was very accommodating when I thought I might have to extend my stay.
The location is very central, only 5-10 mins from Naschmarket and there is a Spar shop across the street.
With the window open, it was a little noisy in the evening at the weekend, but there is always the option to close the window and use a/c instead.
The rooftop terrace is a lovely little bonus and I enjoyed sitting there to relax on days when the weather was warm.
I would definitely use this apartment again and will recommend it to others visiting Vienna.
