This is a great place to stay. It's very central, restaurants and shops are right there. The tram stops in front of the house which is super convenient. It's not that quiet with the busy streets but we didn't mind and slept well.
With only one set of keys it might not be the right choice if part of the group wants to go their own way.
We (4 adults, 2 kids under 5) enjoyed our stay there very much.
