The rooftop bar of the Double Tree Hilton Hotel has the most amazing views of the old city centre. The hotel is the glass wedge shaped building to the east (left) of Central Station.
Head through the reception to the elevator and up to the 11th floor.
Check the prices on the drinks menu before ordering, coffee set me back €6.75!!! But the beer was more normally priced.
It’s open 7 days a week, 11am to 1am
