It was very enjoyable

8.0

The breakfast was excellent and I liked the location. The staff were excellent.

− We stayed in room 259 it was hard to get the shower to the correct temperature, it was either too hot or too cold. Otherwise we were happy.

Aoife · IE · 2026-07-25

Disappointed

7.0

It ws quiet. The Dyson hairdryers. The separate shower/bath. The bedding nd pillows.

− Not being able to confirm late check out until the day of check out. The little coffee bar was barely open. Hot.

Sabine · FR · 2026-07-24

Overall a great hotel , comfortable , modern and in close proximity to M50 , I will plan a return

9.0

Comfortable spacious hotel , excellent facilities , good breakfeast and great TV viewing positions in all public areas

− Breakfeast was excellent but very limited to Cooked Irish Breakfeast, an egg or omellette options would be nice and better quality pancakes Shower was the smallest I've seen in a hotel, terrible design ! Dinner was very enjoyable but portion sizes poor - €8 for approx 8 chips was poor value, as were the €11 desserts ( barely 2 mouthfuls ! )

MICHAEL · IE · 2026-07-23

Very good value and excellent facilities

10.0

Fine

− The marmalade disperser was empty and not refilled.

Breda · IE · 2026-07-21

Can't wait to go back

10.0

Staff couldn't have done enough for us. We arrived with a little one who couldn't cope with the heat and they helped us by letting us change to a room with air conditioning. The Chef also came out personally to discuss the menu with us in regards to my babies allergies. He was willing to make us anything at all.

− Nothing. Everything was perfect
