I stayed at the apartment with my 3 yo daughter, the apartment was perfect. There is everything you might need for a short stay it was just perfect.
Easy access to the tram, safe and clean neighborhood ... Great communcation with Orhan, easy checkin, clean and spacious apartment ...
The only little thing I would note (and it didn't bother me at all) is that there is a busy road in front so it can be a little noisy if you need total silence to sleep. Once again, we had no issue with that but just saying.
I would go back there definitely and Vienna is a gorgeous city !
Thanks Orhan !
