General Review:
Overall, this place was great and I would recommend it to others. It is larger than I expected from the pictures. The pictures don't show that there is a small desk/working space behind the curtain in the bedroom which was a great addition. The overall unit felt very clean. It was great for us (three people staying for a few nights while visiting Vienna).
Amenities:
For the most part, it had everything we needed: pots/pans, bath towels, a good-sized fridge, decent wifi, tv (including Netflix, and more), and a dishwasher. One thing to note is that a few of the listed amenities were missing. Specifically hand soap, basic cooking items (salt, pepper, oil, etc), and paper towels. It also only had one extra toilet paper roll and a single dishwasher pod. None of these were a big deal, but would have been good to know ahead of time, so we could have gotten them before realizing they weren't there when we needed them.
Accessibility:
The apartment has great natural lighting. The elevator is also nice. However, if mobility accessibility is important, this place isn't super accessible because to get in the shower you have to step over a very tall bathtub. The bathroom with the toilet is also very small which may be an issue for larger people. It is close to many restaurants and transportation to the city center. It is also off of some busy streets so outside noise was on the louder side if that is something that is bothersome to you (it was fine for us). Also, sometimes people would smoke right below the windows, so we often had to close them to avoid the smell coming inside.
Communication:
The check-in instructions weren't sent to us beforehand. We ended up having to call the host while we were on the bus 15 minutes away, so we could get the info on how to get the key. To be fair, we definitely could have called earlier, but if you stay here, it would be worth checking if you have the info before arriving at the apartment. He did answer the call right away and sent us everything we needed.
