We booked "The G" on basis of good reviews and also a previous stay - 14 years ago! This was a mid-week stay.
We were allocated room 106 - in the corner, centre of photo of the front of the hotel. Still smelling of new carpet, the room was spacious, elegant and well appointed.
Parking in the allocated hotel parking wasn't a problem. Staff were welcoming, friendly and helpful. We had no problem with carrying our suitcases up the stairs, but are not sure if there is a lift for less-able people.
We had both our evening meal and breakfast in the hotel, which is recommended.
The only minor detractions were finding a previous occupants blindfold/eye-shade under the side-table in the room and no decaf coffee. We had been worried about noise from the road junction outside, but had no problems
Highly recommended, this will be our first choice when we are next in Mt. Gambier (hopefuly less than 14 years).
