Before I made the reservation, Eva, Michi & Friends always answered my many questions promptly, leading to my choosing this particular apartment among their several listings. When I needed to extend my stay not once but twice, they were also most helpful.
I ended up staying 9 nights in the “Santorini”, but don’t need to repeat all the good things everyone else had already said about it!
The only things I would add:
1. The Billa supermarket only one short block away (at the corner of Rilkeplatz and Paniglgasse) was most convenient, open Monday-Saturday till 20:00 (8 PM) but closed on Sundays. If you like Mozartkugeln / Manner wafers but don’t want to pay Kärtnerstrasse “tourist prices”, this is where you can stock up to your heart’s content!
2. When the weather turned unexpectedly rainy, cold and windy (rather unusual in mid-May), it was a godsend to come back to/just stay inside a well-heated warm home 😃 .
