suzannaIMBeautiful hotel
Beautiful hotel set in picturesque surroundings. Our room was large with a comfortable and was very quiet. We ate in the bar restaurant twice and both times the service and food were excellent
KariFinlandPricy, hot and badly ventilated room run by nice and helpful staff
Staff is basically ok and they have a way to send you WhatsApp message after first day and asking your satisfaction level - kind of nice. However, if you ask and you get 3 or lower on the scale of 1-5, then one would…

Questions about Castleknock Hotel
What time is check-in and check-out at Castleknock Hotel?
Check-in is from 4:00 PM. Check-out is by 12:00 PM. If you're arriving late, tell us and we'll ask the property to hold the room.
Does Castleknock Hotel allow pets?
No — the property states that pets are not allowed.
Is there parking at Castleknock Hotel?
Yes — the property states that parking on site is free. Whether a space can be reserved in advance varies, so we check it against your dates.
Does Castleknock Hotel have a pool?
Yes — a pool is listed among the property's facilities. Seasonal closures are common, so we'll confirm it's open for your dates.
Is breakfast included at Castleknock Hotel?
Breakfast is offered at the property. Whether it's included depends on the rate — the board type is shown on each room once you put your dates in.
Does Castleknock Hotel have Wi-Fi?
Yes — internet access is listed among the property's facilities.
Can I book a block of rooms at Castleknock Hotel?
The property lists meeting and banquet space, which usually means it handles group business — but how many rooms it will hold at once, for how long, and at what rate are set case by case and are not in any feed. Tell us the dates and the number of rooms and we'll get those terms from the property in writing before anything is charged.
Does Castleknock Hotel have wheelchair accessible rooms?
The property lists step-free or accessible facilities. That flag is the one least able to settle the question: a hotel can carry it and still have a step at the entrance, or a bath rather than a roll-in shower, and it does not say whether the accessible room is free on your dates. Tell us what you need and we'll ask the property directly rather than reading you the flag.
Can I check in late at Castleknock Hotel?
The property lists a front desk staffed 24 hours, so a late arrival should be possible. Standard check-in is from 4:00 PM. Rooms are still released after a cut-off at some properties regardless of the desk hours, so tell us your arrival time and we'll have them hold it.
How do I book Castleknock Hotel?
Put your dates in above and book online, or call (888) 789-8585 and we'll do it for you — including things a booking form can't handle, like a block of rooms, a monthly rate or an invoice for your employer.
