Hi, I don't think so for the TV. For teh shower, don't worry you have the small one at hand but also the main one above.

6 stops on the ubahn which is about 10 minutes journey. Trains every 5 minutes take you directly into the centre. By cathedral. There is one Xmas market outside st Stephen’s cathedral. Others in walking distance or a quick change to another line. The ubahn is 5 minutes walk and you can buy tickets on line. We bought 3 day ticket on phone but it was never looked at . Concierge will give you a little map which is very easy to read. Biggest market is by city hall about a 15 minute walk if you like walking.
