I stayed at Wolfgang's place for 1 month and i must say it has been a pleasant experience. Apartment is at a great location - Vienna General Hospital is just 1 minute walking distance, metro station is also quite close and City centre is just 10 min walking distance. All the major grocery shops, supermarkets are nearby. Apartment is very clean and has all the amenities with fully equipped kitchen. Though the building is located on main road but flat is very quite without any noise. Overall, it was pleasant staying at this apartment and Wolfgang is very responsive host. I would surely recommend this apartment to others.
