Pros: Apartment is large, clean and beautiful, just like the photos. Area is quiet and close to the metro. There is a market right across the building. Around the corner is a shopping street with many stores and places to eat. Mattress is very comfortable to sleep in. Everything was available that we needed - iron, hair dryer, utensils, cups and plates, toilet paper, etc.
Cons: The shower didn't give out a constant stream of warm water and the kitchen stovetop was slow to heat up but it's not a big deal. Pillows are a bit soft and would probably be nice if stuffed into a smaller sized pillowcase.
Veronica is very communicative and checked in on us to make sure we were comfortable. Would stay here again if I'm ever in Vienna.
