We had a great experience at Lila & Sid's apartment. The place is very welcoming and it is quite comfortable even for 6 people. Very spacious and very clean.
It is also very warm during freezing cold Vienna winter.
They are super hosts indeed :). We were warmly welcomed although the late hour of arrival with useful info about the place and the neighborhood. They even have a booklet prepared for guests with basic info for people visiting Vienna :).
The complimentary bottle of wine was a very nice surprise :).
During our stay they kept in touch just to see we are not missing anything.
The neighborhood is very convenient, with lots of stores and even places to go out or grab a bite late in the evening(there are some good
Turkish fast foods nearby).

Overall, a very nice experience with good value for money.
