My mom and I stayed at Sandra's apartment for 5 nights in August.
First, let me start with the positives.
(1) The apartment is well located. It is easy to reach from the airport (approx 30 min taxi ride) and within walking distance of a tram station, metro station, and bus station too.
(2) The apartment looks the same as conveyed via the pictures. It is neat and clean. Quite a cute space and I enjoyed living here.
(3) Sandra offered me a self check-in which was very easy to do. We had no issues.
Now, I would also like to put down the things that were not quite upto my expectations.
(1) The WiFi is extremely, extremely slow. There is close to zero connectivity in the bed room and very slow, often frustratingly so, connectivity in the living room. We were lucky to have had mobile data. However, if you do not , you might want to take this into consideration before booking your stay. I really hope the WiFi is improved at the earliest
(2) Second, we were not able to access the garden. There are two doors in the living room that open into the garden -- one of them was locked and covered with a table; the other appeared to be broken. Long story short, we could not step into the garden for even a minute during our stay of five days. I messaged Sandra regarding the same but did not receive a response. Since the garden is one of the reasons that I booked the place-- it was something that set this place apart compared to other listings on Airbnb, this was definitely a huge disappointment. I felt as though I did not quite receive what I had paid for.
I would also like to let you all know that the apartment is not quite on the ground floor-- more like a lower ground. You have to climb down two short flights of stairs (about 20 steps in total). This was not really a deal breaker but just be careful in case you have heavy luggage and expect to step right into the apartment on the ground floor.
All in all, I was happy with the space and location, but really unhappy with the wifi and garden situation. You can weigh the pros and cons for yourself in case you are planning to visit Vienna.
