Just stayed here about 2 weeks ago for one night. Cheap rate. The shuttle ran every 30 min, which is fine, but could be sooner it's only a 10 min or less drive. In that time I saw all other buses come 2 or 3 x. As others mentioned still 2 Euros to come back free to go.

Diamond recognition, was free breakfast, 2 bottles of water, a free drink at the bar and wifi. Nothing else special.

Breakfast was fine, plenty of hot and cold options, so I was happy.

Staff were friendly and had a good map of downtown, plus they knew what buses went where (and where to catch them). It was 3.20 to get to O'connel st and 2.60 to come back, still not sure why. But vs 20-30 for a taxi one way a great deal.

I have a ton of pictures and a more detailed review here if interested.
