Landscape around the hotel. Solid breakfast with plenty of food variety to choose from. I liked hotel interior design

Swimming pool appearance and condition was below my expectations.

"Potentially a good stay but let down by overpriced bar food which wasnโ€™t good. Stayed in a single occupancy room, 128. B"

7.0

Very nice hotel in a very nice location.

Bar food wasnโ€™t fresh, chicken wings and chicken fillet green curry. Chicken tasted old and rubbery. Very overpriced!!

"Dissapointed !!"

6.0

Booked a suite back in January to stay for my birthday in May. Emailed March to ask if possible could we have a view of the lake. Travelled today got there at 10, where we were able to drop our bags and explore Dublin. Came back at 3.30, room not ready which was fair enough with check in at 4. At 4 my husband asked what was happening. After a bit of faffing about we got our key. The room is absolutely stunning, until you look out the window. No lake or even a golf course view but instead you have the car park !! Phoned reception who informed me there was no suites with a lake view. Really !!! Duty manager came up and showed us another room with a view of the golf course. But this was definitely not the same size room which we had paid for. So had no option but to stay where we were. I understand requests can't always be given. But come on when your paying over ยฃ600 euros for your room at a stunning location you don't expect a car park in front of you. Felt this could have been dealt with better. When booking maybe request not to have this room ๐Ÿค”
