I will be in vienna for only two days, then to salzburg. my question is where in the world can i rent a cooter? or are there scooters to rent in vienna? i am unable to locate to figure that out. and where is the cheapest market to buy my bread and meat so i can make my own sandwiches?
Rick's guidebook mentions several supermarkets in with his hotel listings, by neighborhood. They include the chains Julius Meinl, Billa, and Merkur. Any staff at your hotel, B&B, or hostel should be able to point out what's closest to their location, or I also use Google Maps for such a search. Bike rental is more common than scooters, and Segways also seem to be an option, but public transport works well.
I'm with Laura and don't think that you need a scooter in Vienna. Most things are centrally located and within easy walking distance. And, those that aren't can be reached by public transportation.
Look for the nearest Aldi's in Vienna. They are in Europe and in the USA too. As for a scooter, the Le Meridien Vienna rents them as does the Ring Hotel and the Hotel Daniel Vienna.
You find bakeries everywhere in the German-speaking world, and the bread is usually pretty cheap. No more than €2 per loaf. They will slice it upon requested ("Scheiden").
Inner city supermarkets don't always have an attached bakery, but those in the outer districts almost always do. As noted, Aldi and Lidl will be your cheapest source of cold cuts.
