How to read the data

• All prices are EUR totals for the full stay and include 13.5% Irish VAT. There are no mandatory extra fees.
• A stay needs every night from check-in through the eve of check-out to be Available. Minimum stay is 1 night unless a date notes otherwise.
• Prices are set dynamically and can change daily; quote the price with its date and treat quotes older than a day as stale.
• Check-in from 3:00 PM, check-out by 12:00 noon. Sleeps 2 per room except room 303 (sleeps 4) and room 306 (sleeps 3).
