I was there for a short study abroad (2 weeks) and had an amazing experience! Florian is really a great host and i’d definitely recommend this place to other travelers.
It’s about 15 min walk from Vienna university (specifically the law school). Overall great location with plenty of restaurants and you can pretty much walk to major sighs within 20/25 min.
Room is pretty much in its own section of the house that can be closed off so very private for a shared apartment.
