Arabelle's studio is cozy and an overall great place to stay for a few days. The location is absolutely amazing, close to everything you need in Vienna - whether it's sightseeing or bars/places to eat.
Check in was smooth, Arabelle's friend met us and gave us all the needed information and overall communication previous to and during our stay was easy and fast.
The place is also super warm and has most of the things you'd need during your stay.
My only recommendation would be also adding the basic necessities in the bathroom - shower gel, shampoo etc.
Anyway, fully recommend this place for your stay in Vienna - it's nice, sweet and close to everything you need :)
