Customer Feedback

I ordered these flowers from America to be sent to my cousin in Dun Laoghaire for a very special day in her life. They were delivered promptly and courteously, and she was absolutely delighted with them. I thank the professionals at Costello Flowers for their good service, as well as for their follow-up in confirming the delivery…..

The flowers were beautifully presented and contained a wonderful assortment of flowers. Would definitely recommend this florist and using this service…..


My cousin was thrilled with the Amber bouquet from Costello Flowers which arrived promptly on her birthday morning.

She is very knowledgeable about flowers and plants and said it was absolutely gorgeous .

Thank you Costello Flowers
