Ari was a great host and he responded almost immediately.
He has a list to share regarding the most attractive places in the neibourhood and in Vienna general. Tried some places, which were nice:)

I think of all my experience with AirBnB, this was the fastest get in into the apartment without host being present. Instructions were clear and understandable.
Apartment itself was very clean and renovated with a style. Very convenient location (close to the old town). I warmly recommend for people looking for nice, small and cozy apartment. You will get fresh towels, coffee and tea.

I would stay once again for sure.
