What fantastic hosts Kati and Bernd were. The apartment was exactly as advertised and was extremely clean and comfortable. It is in a quiet, safe neighborhood of families, lots of kids and people walking dogs, but close to transit lines that made it easy and fast to get anywhere in the city. Many grocery stores are located nearby, within easy walking distance. Lidl is just 2 blocks away and had most of the essentials, but seemed to be a bit hit or miss depending on when I visited. Merkur was a little further away but had a more complete selection. The kitchen was fully equipped and I cooked many meals. The TV and internet setup was flawless, the bed was very comfortable, and the bath and shower were spacious and well stocked with necessary items. When I arrived 4 hours before check in, Bernd was gracious in allowing me to store my luggage in the apartment while it was being cleaned. There was a chair in the living room that was broken and unusable, but Bernd was quick to replace it with a new one when I let him know. He visited with me to welcome me to Vienna, and graciously spent nearly an hour talking with me and discussing this amazing city. On Bernd's recommendation I visited s'Schmankerl-Eck about 3 blocks away, and the food was excellent and reasonably priced. Also visited Pizzeria Madera about 4 blocks away, and it was outstanding. Also recommended - Gasthaus Kopp, a short U6 ride north (Jagerstrabe 2 stops to Handelskai, then a 3 block walk), that had the best wiener schnitzel I have ever had. More schnitzel than I could eat and 2 glasses of wine were $17, cash only. Very homey and comfortable. Getting to and from the airport was quick and easy. Take to S7 train from the airport to Handelskai, then the U6 from Handelskai to Jagerstabe, then a 4 or 5 block walk.
There is also a laundry in the basement of the building that was easy to use.
I cannot recommend this apartment enough, and would happily stay here when I visit Vienna again.
