We stayed at Navneet's place for a few nights, the apartment is so close to everything (tram, U-banh, bus stop; we mainly use tram to go around). There's an awesome bakery close by (a few minutes walking) called Felzl, highly recommended!
The apartment itself is clean, spacious and pretty much matches what is described. The patio/garden is a plus; enjoyed our dinner out there. There's a small market right next door, so if you ever need anything it's just a few steps away.
All in all our stay was great, would go back to stay at his place again if I'd have the chance to come back to Vienna :)
