Breakfast is fine. It's a normal buffet; nothing special. Eggs are made to order.

I didn't know about the free shuttle but you are about a 3-5 minute walk from a station on the "new tram" line. As usual Google maps will tell you what to connect to for wherever you want to go. It's going to take you half an hour to get anywhere but other than that it's convenient.

The annoyance is that all the public transport ends at midnight (that is, the last train arrives at the end of the line at midnight) so if you are going to be in the city and out past 11:30 or so you will end up needing a taxi to get back.
