It was really a pleasure staying here. The apartment is stylish, super clean and comes with everything you might need. It's also super close to the Underground and a Supermarket, so your needs really are covered.
Simin and her sister (who was nice enough to help us with the check-in even though we arrived at a bit of a late hour), were super helpful and nice and answered all our questions.
I would for sure recommend this place to other travelers and I would stay here again on future trips to Vienna as well.
