Just amazing, in every way! We had just the most perfect day for our wedding at Caswell House. Anna, Sarah, Courtney and the whole team were so brilliant from start to finish. The whole lead up to our day, they were so attentive, easy to work with and focused on helping us to have a great celebration. All the staff were so polite and friendly, they made it easy for all our suppliers to set up and do what was needed. Everything about this venue is absolutely amazing and we are very lucky we found it!
