The apartment is just as described and shown in the photos. It is located on ground floor, so if you can't bear little bit of noise from the road, this might not be the best space for you. We are fine with that so there is no problem. The main door to the apartment leads you straight to the bed/living room. You can close the curtains to avoid seeing lights and shadows from the outside (the windows are not transparent anyway so no privacy issue). The sofa bed is quite comfy.
The kitchen is spacious and fully equipped. We did cooking once and we had everything we need. The bathroom is relatively smaller, compared to the kitchen. You need to be patient with the hot water, as it would take a while (5-10mins) for the water to heat up. The shower head has a bit of water leakage problem. Other than these, the bathroom is fine.
Betty is a really easygoing and friendly host. Very responsive and communicative. During checkin, she spent quite some time to tell us about Vienna, like what to see, where to eat, transport and all that. Since it was a Sunday on the second day, she was kind enough to check the groceries that were still open. She also recommended us a really nice local gelato shop, and the ice cream was really good!! Thanks very much Betty!!!
