Justina's studio is fantastic!
It is very clean and cosy. The decoration is inspiring, the bed is comfy and the shower is a bless. The kitchen has everything you need - even edible bits and bobs. She leaves you surprises and treats, which helps make you feel at home!
The flat is very close to the main train station - so much so you can actually walk there! Or if you'd rather save your legs, there's another station even closer! There are also nice cafés in between stations.
I would recommend Justina's place to everyone, and will definetly stay there again if I visit Vienna again!
