We stayed in this apartment last Aug and thoroughly enjoyed our visit. The amazingly well equipped and comfortable apartment is located in an older apartment block which only added to the atmosphere. Slightly out of the centre but very well positioned for public transport, underground, trains and buses. No need for a car - once we unpacked our luggage we parked in a long stay car park not far away and did not use the car again until we left for the next part of our holiday.
Ingela, the owner, was very helpful and always contactable as and when we needed her. My teenage daughter left her favourite tee shirt and Ingela promptly posted it home (thank you).
We would recommend this apartment to anyone planning on visiting Vienna.
