We stayed here on New Years Eve and despite the hotel being very busy and very full - the staff were fantastic, very helpful with our enquiries at check in and the concierge was able to help us with information about restaurants. Very down to earth, very friendly service with bags and hotel ammenities, including the bar. We managed to secure a late checkout/day rate for a very reasonabe cost the next day as we had a late flight out of Adelaide. Though it was not the cleanest hotel I have ever stayed at - and the room was quite small and dark, the great service left a super impression.
The pool area is a bit tired and needs a refurb - not truly 5* surrounds, but the service was 5*+.

I stayed here with my Dad for two nights and we had a really great time. This hotel is in a great location, right on North Terrace, which also features the wonderful museum (excellent cafe, do stop for lunch there), art gallery, entrance to the botanic gardens and many more attractions - so it's impossible to get lost. Adelaide as a whole is very accessible and compact and extremely welcoming.
Our room was spacious and very clean, the bathroom as well. Breakfast was very high quality. The service throughout is excellent. Outstanding though was the service we had from Marco, the concierge. He could not have been more helpful or friendly and gave me a whole new outlook on what a good concierge might be like: all too often asking a concierge a question can be a bit of a challenge, but not at the Sebel.

We revisited this great hotel, again in November 2006. We were not disappointed. They greated us as old friends, and recalled our previous visit. As we were staying for 5 nights we were given a free upgrade.
We are going back to Oz in late 2008 or early 2009 and we will definately stay at this hotel..

Close to convenient bus stops, the railway & within a few minutes walk of the centre. What more could you wish for?

My husband and I stayed here for just one night during winter. Our room was very clean, and very spacious, and had the usual mod cons, but the decor seemed slightly old and tired, and I didn't think there was anything luxurious or different about our suite really.
I think I was expecting something quite special judging by the hotel's stars and judging by the price you pay to stay there, but I found the room to be fairly standard.
Of course, this could have just been the suite we stayed in. The rest of the hotel may be different - we stayed in a deluxe suite with a spa.
However, the breakfast in the hotel is excellent! A varied choice, with very helpful staff.
If I was to recommend this hotel, I would say it would be ideal for a short stopover whilst on business, or for a short stay for tourists passing through Adelaide. I would not recommend it for a romantic getaway or a honeymoon.
Overall though, our time there was fine.
