The apartment is very clean and spacious, newly renovated and has a kitchen equipped with pretty much anything you need. Everything looks much better than in the photos.
The area is very quiet and safe and can be reached from metro station S6 line in less than 10min. There are a few supermarkets around and even a marketplace.There is a small bakery run by a turkish family, they make great bread and other goodies - don't know the name though :(
Schonbrunn palace is in a short walkng distance, maybe around 20-25min.
Both Laszlo and Vilja are very nice and very prompt to reply to the messages. I recommend staying at their place.
