Vania's apartment was perfect for our stay over Christmas. It's perfectly situated close to WBH station and the shops on Mariahilfer Strasse and there are some good restaurants close by (try Tata if you're wanting a quick and easy Vietnamese meal).
The apartment itself is a great space with quirky touches. You have absolutely everything you could possibly need - and more (fantastic coffee machine, sauces and spices, a Wii console (!), first aid kit, chocolates and more).
Communication was great, the place was very clean and tidy and the bed in the living area is super comfy!
Thanks for a fantastic stay. :-)
