Venue Testimonials

My husband and I were lucky enough to be invited to a wedding at The COMO. We decided to also stay the night as well. The Venue and food was amazing and the staff went out of their way to make you feel special. The Heritage Balcony room was amazingly spacious and well appointed.

What a slice of pure indulgence! This would be the most luxurious accommodation I have ever stayed at. The inclusions in the rooms, the friendly and attentive staff and of course the great pool. This was the best conference I had attended and I know the COMO was a huge part of that! Do yourself a favour and book in, you won't regret it!

Stayed here as part of the bridal party for a friend's wedding and must say the building is stunning, wonderful additions of modern technology in this heritage listed building. Each room is slightly different and luxurious with beautiful city views and the central location was fantastic. The staff were fantastic and helpful and happy to help however they could.
