We stayed at Ingela's place for our 10th Wedding anniversary, and it was perfect. We were 2 adults and an 8 year old boy and we were very comfortable. Even if were 4 people we would have stayed comfortably well.
Very very clean and there are those little extra touches that make you feel home immediately.
The area is very safe both during the day and night, and very easy to travel to all parts of Vienna from there. The fact that it is 5 minutes walk away (literally) from a sub-way (Meidling Haupstrasse, U-bahn) made our stay in Vienna, extremely easy.
It is also very close to groceries, supermarkets and veggies shops.
For Vegans and healthy conscious people there is a very good and reasonably priced, Bio-Supermarket with a large variety of Vegan and organic products.
Ingela was very helpful and whenever we needed any help/tips, she responded very quickly.
Looking forward to go again.
