from the hotel's web site:

Arriving by train:
At the central station you can use the bus or tram.
Bus: take bus M 11 and exit at Packhof.
Tram: take tram S 1 and get off at Hagenmarkt.

From the hotel to the TU it's less than half a mile. Depending on your destination at TU, M3 could be a good choice, walking is another.

Can't comment on restaurant and pubs, sorry.

Enjoy your time here
