The hotel is in front of the train station, very good location, making it easy to come and leave the city by train, close to take subway or tram.
The hotel is very nice, good room, good breakfast, gentle receptionists. The hotel had a lot of families, many kids, the breakfast area was out the table quickly but the novotel team was always including table to accomodate the people on breakfast (around 9h30-10), but if you come earlier the breakfast area had a lot of free table.
I believe this was due to the new year vacation. If I have the chance, I will stay in Novotel Wien again :)
