Liz & Jules' apartment is precisely as they describe it online. It's strategically located to destinations that visitors are keen on visiting when they are in Vienna. Walking distance to Stephansplatz, grocery store is nearby, and tram, U-bahn, bus stations are all within walking distance.
The apartment itself is clean, complete, warm, and there's hipness to its overall atmosphere.
Liz is helpful, informative, and friendly. Very beneficial for first time visitor to Vienna.
In all, it's strongly recommended.
