As a quick summary, Janko’s apartment is fabulous and highly recommended! It’s in a historic building with beautiful old stained glass and tiling in the common spaces. The location is great, it’s in a neighbourhood that my friend who lives in Vienna recommended to visit and wander around as an attraction as there are so many nice shops, cafes, restaurants and bars. These are spread out a bit though and don’t seem noisy or oppressive, it really is a cool area. For breakfast there are 2 good bakeries within a 5 minute walk and loads of brunch places (and for dinner and lunch lots of cafes and restaurants too). Although it’s on what seems to be a fairly main road the apartment is really quiet and there are black out blinds as well as normal blinds for sleeping. Vienna is very easily accessible from the apartment, with the Museums Quarter and 2 metro stations a short walk away.
The apartment itself had has everything you might need, including a comfy bed, a coffee machine (dolce gusto and pods) and all the utensils etc. you need to cook a meal (we did once- we had to get an early night and wanted to spend some time in the lovely apartment), the towels and bed linens were good quality. It is very stylish and minimalist, we absolutely loved the parquet floor, high ceilings and cool light fixtures throughout. The shower was good and the bathroom stylish and clean.
Janko was a great host. He responded to all communications super quickly, was friendly, kind and helpful (including in arranging smooth check in and out and leaving water and chocolate for us) and he provided lots of useful local tips for food, bars and supermarkets etc. We loved our stay in Janko's apartment, thank you Janko!
