A group of 7 of us stayed at Corrina's Haberlgasse appartment for the 1th May holiday. The fabulously renovated apartment is in a lovely old building, has 4 separate bedrooms, a bathroom, 2 toilets, a well-appointed kitchen and a private terrace and a vaulted party cellar. The street is quiet but very near a bustling multicultural neighbourhood. The nearest tram station is 50m away and there is a laundry service 50m in the other direction. The only thing missing was wifi or any kind of internet access, but I'm sure that will be amended soon.
Corinna is super friendly and helpful and made our stay comfortable and hassle free.
