We stayed for two nights to visit VIVID. The location is perfect. We could sit on the balcony and watch the displays across Darling Harbour, all the way to the Harbour Bridge. There is a bit of traffic noise, but it's the city of Sydney. You have to expect a bit of noise. It certainly wasn't intrusive. The bed was very comfy but I'm not sure about sheets with no doona cover. The shower and bathroom is glorious. It took me a while to find a couple of light switches but I should have read the instructions I was sent. They are on the control panel next to the dining table. Check in was super easy with 24 hour concierge service. Communication from the host was first rate.
Location - There are stairs beside the accommodation that lead down to the Harbour but we needed an elevator. If you get off the main elevator at level two, go to the glass door, press the green button to exit and turn right. There is another elevator that will take you to ground level. There is a small convenience store about 30 metres away to get milk etc. The Opera House is a 5 minute walk. Grab an Opal Card for the public transport. It's cheap and the best public transport system I've used. It can be used on buses, trains, light rail and ferries. Grab a ferry from dock five around to Darling Harbour to explore there. The light rail runs from there to the casino. Walk to the Chinese Gardens which are a must see. Keep walking and you'll end up at Paddy's Market. We spent a morning riding the ferries, just sightseeing. It's the best view. Go at night for an even better sight. Once you reach nineteen dollars (at time of review) on the Opal Card, any extra travel for the day is free.
Overall we had a great stay, made extra special by the accommodation. We hope to be back for a longer stay.
