This is a nice, clean little place in Vienna that's suitable for a short getaway.
Good things:
1) Great air conditioning, which was essential for us as we visited Vienna during a heatwave.
2) Drip coffee machine. A nice touch.
3) Shower pressure was delightful.
4) The location, albeit perhaps not central depending on your definition of such things (it's about a 15 minute walk from the town centre), is safe and quiet.
Neutral things:
The kitchen is not really for cooking: very limited worktop space, two hob rings, and a microwave are available, but there is no freezer, toaster, or oven. This was not an issue for us, as we had a cold breakfast in the mornings, and then ate out during our stay. However, if you're planning on cooking during your stay here, you will need to plan carefully.
Not good:
1) The pictures are slightly misleading in that the beds are single beds with chunky frames that prevent them being cleanly pushed together.
2) The mattresses are very, very soft, and may cause discomfort and difficulty during the night.
3) The wifi is slow and intermittant: expect to use cellular data for a significant portion of the time.
4) No blackout curtains, so it does get bright quite early. If you're planning a leisure holiday in the summer, we'd recommend bringing an eyemask.
5) We also felt the cleaning fee was quite high for the size of the apartment (£22 for roughly 400sqft).
