As mentioned in nearly all reviews here, we couldn't have a better host than Leena! She welcomed us with tea and a typical Indian sweet, provided directions on how to get to places in Viena and paid attention to each and every detail to make us feel at home.
The communication was also very easy as her English is great (not so common in Vienna). She was flexible with both the check-in and the checkout.
The house is comfortable and the room is huge - it has a desk if you need to work. It was warm, the linens were smelling good and everything was tidy.
It's not close to the city centre, but there's a bus stop right next to her house (less than 3 minutes walk). Taking the bus and the subway, you reach the main attractions in Vienna in about 30 minutes (it was very easy using the app Moovit or even following Leena's directions).
Also, in case you're a sushi lover, there's a sushi place 7 minutes away from Leena's place (by walk) where you can have all you can eat running sushi for 10,90 euros at lunch (this price is valid for weekdays only).
I definitely recommend it for anyone visiting Vienna! Thank you, Leena!
