I have stayed at Claudia’s place for a couple of days. The place was super easy to find (from a train station)
The place was nice and clean; room was spacious but cosy, bathroom/kitchen clean.
I have mainly walked to/from town…its about 10mins to Belvedere palace and about 30-40mins walk to town centre.
It was nice to have a friendly landlord. Claudia gave me enough informations and tips for me to go around Vienna. Definitely would stay again.
