Excellent Stay! The apartment was great! It was clean and superbly equipped.
Special thanks for the host(I apologise I don't know her name!) who was so helpful in receiving us. We were stuck in a queue for over 2 hours due to which we reached Vienna at around 2 am! She made alternate arrangements for us to get us the key! Very communicative and helpful.
For others coming to Vienna, be prepared about the parking rules and regulations before coming. Mark the park houses in order to park there in case public parking is occupied. It is recommended to buy a park permit in the reception to park in the day time near the hotel.
To conclude, great stay and hence I highly recommend this apartment.
