This is a great cheap option for Vienna. It’s a little far from the “action”, but it’s quiet and there’s plenty of close public transport. The apartment wasn’t exceptionally clean, but the sheets and towels were fresh. It gets a little hot at night. There’s a fan provided but it doesn’t work great. It was great to have a kitchen stocked well and a nice bright living space! The wifi works pretty well. The shower is unfortunately small and difficult to do much in since the shower head points directly at the shower curtain, but it was manageable.
Overall, a good choice if you want to do Vienna cheaply!
