Very good location. Room is very spacious and comfortable. Small tube of dish washing detergent and 2 small packets of milk were provided in the room. Very thoughtful gesture as it saves us short vacation travellers a lot of hassle of buying from supermarket and reduces wastage because we used to buy for just a few days' use and had to throw away big bottles of detergent and milk.

My husband and I stayed in Sofitel for 3 nights and everything was honestly 10/10. The staff are excellent - so friendly and helpful. They attended to all our needs. Special shoutout to Nia and Kla for being so friendly :) The place itself is luxurious and all the amenities were fantastic. The buffet was just phenomenal - they had everything you can ask for! One of the best breakfast buffets we have had and we have travelled all over the world. We felt spoilt for choice. We loved our stay here and definitely would highly recommend!! Oh and I can’t forget to mention that the location is super convenient surrounding Darling Harbour and Cockle Bay Wharf - had several places to eat and just an overall beautiful atmosphere.

Great hotel! Location is near train/metro/tram stations, the hotel is clean and the room is very spacious (Tower Deluxe Double - the double bed is quite big for my toddler and I). Honestly the service is not the best, I think the floor managers and service staff need more training especially for Asian customers. I was called “the Asian guys” by the doorman and my friend was treated unfriendly, but he was so polite to white man beside us. Funny.  But otherwise, great stay :)

Location was perfect, room is very spacious with a proper work table. The only downside was the flight of stairs at the entrance which is not friendly for heavy luggage. While the staff will lend a hand, still good to have flat ground.

Very nice and helpful staff. Good bedding. Excellent location. Note there is a bar next to the hotel that can play music until around 11PM on Thursdays to Saturdays evening. So bring earplugs and/or ask for a quiet facing room (there are some looking towards the inner courtyard) An extremely good price for value

We loved our room, it was very homey, clean and comfortable. We also loved the pool, would have been nice if it was heated. Housekeeping made sure the sheets were changed and cleaned everyday throughout our stay, we appreciated that. Buffet breakfast was nice and staff were lovely and accommodating. We also would like to thank Tasha for making an effort to look for our missing charger and for resolving the issue. We would definitely stay at Mercure Sydney Liverpool during our next visit in the near future.

We had a fantastic stay. Right in Darling Harbour, we went to the maritime museum and aquarium and animal park and the imax cinema. We went to the little snail restaurant. Yes there is a construction site in front but from our room you could still see the water and buildings lit up at night and I didn’t mind watching the cranes at work. I have to compliment the hotel on the temperature of the room, it was perfect, we didn’t touch the aircon control at all.
