Never done this before but was staying one night in Sydney for business,left it late to book so chanced the Wotif Mystery pack. It said it was a Hotel at The Rocks and as my work was down that way and price was good thought I would take the chance.
Turned out a very good choice. A nice little quaint boutique Hotel, in a very convenient location, good and attentive staff, well decked out rooms (if a little small but was only me so no problem I understand other rooms are larger) and very well priced.
I will be returning again next time in Sydney and booking direct with Hotel. They have promised to match any other price offerings. Part of the ACCOR Group.
If you dont need all the trimmings of a large Hotel and location suits very hard to fault.
