Outstanding place, everything much nicer than we expected.
We did not get to know Marianna but Stefanos is very friendly and nice.
they even offer the first breakfast, coffee and anything you would possibly need in a kitchen.
The apartment is very cosy and nice decorated, spacious and in a location near metro, tram and all kind of shops.
They provide extra bedding and towels and towels, shoes for inside the apartment, a map of what is around.
We are definitely staying here again the next time we come in the city and will recommend the place to anyone who wants to visit Vienna.
