Gary was very responsive and helpful. He was also very professional about the rules and regulation of the apartment...
Apartment is well connected by trams...and Ubahn and getting around Vienna is Extremely easy...there were restaurants and pubs all around the apartment which was great...apartment was clean and well decorated...internet was fast and reliable..bathrooms were nice and clean too...

However, the apartment was not a fit for our travel group because of the following issues
1: the small bedroom do not have a ventilation and it was hot in Vienna in July ...the small bedroom was also a little damp...
2. I asked Gary to provide a fan but he could not provide it and advice me to keep the bathroom doors open which was not feasible for our travel group due to privacy issue
3. Large bedroom had two nice and comfortable beds but it was noisy at night because the apartment is located right beside a street...
4. There was no locks in both doors of the bathroom which was very inconvenient for us.
5. We had two infants in our group and we had to keep the showpieces out of their hands to avoid any hazards...

overall i would not recommend it for two families with small kids...but for one couple or group of friends it is ok...though the trade off between small and large bedrooms are great...and most people will not like the small bedroom...
