The best local flower shop, great advice and service every time. I use Costello's for all my personal and professional... flowers, they did my wedding and every occasion has been perfect. A lovely friendly team, Ann and Helena always have great ideas on the best flowers to send and my daughter can't pass the door with a big hello from whoever is there that day!read more

Costello Flowers are one of the most valuable jewels in the crown of Dun Laoghaire local business. We have used them... for weddings, funerals, and just spontaneous floral moments. Every time we've sent flowers from Costellos', I always get comments remarking on the beauty of the bouquet. They also give excellent advice on the different types and what to send when, and the staff are highly personable. I genuinely look forward to visiting the shop in person. Highly recommend.read more

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…..
