I spent almost two months in Monika and Helmut's place while I found a permanent accommodation in Vienna and found that absolutely nothing was wanting. The subway and the tram are just a few blocks away, as are a couple of supermarkets and pharmacies.
The apartment was exactly as it looks in the pictures; it's kept beautifully clean and it has everything one could need for a comfortable stay.
Monika and Helmut were extremely prompt to answer my queries and very flexible when I needed them to be. They made what could have been a stressful first couple of months in Vienna very smooth. Thank you!
