The apartment wa excellent -
Right on the metro, easily reachable from Airport and city center and every conceivable attraction.
It was also *spotless* and exttemly well kept and furnished, with great style if I might add.
However, all thia pales in comparison with Hannes -
He took such great care to explain everything, from arrival instructions to sightseeing to great cafés, with carefully crafted itenerarries and cleqr instructions, to the point it felt we found our very own tour guide.
He even went to great lengths helping me set up my prepaid SIM.
I cannot recommend Hannes or his apartment enough, but I'll try - if you go to Vienna, this is the place to stay, look no further
