Staying in room 220, reasonable rate and not bad overall with a lot of potential with better management but..
Good - Housekeeping does a good job with the basics, clean, well presented, reception polite and friendly convenient location and onsite parking.
Bad - Let down by what appears to be long term inattention to basic room maintenance...door handles coming off, loose tapware in bathroom, sticky doors, water dripping down from aircon above during night making sleep very difficult (reported but not attended to), Roof top (staff?)relaxation area outside my window has dirty glasses and empty beer bottles left there unattended for at least 3 days so far.

I stayed there for 4 nights. The hotel was busy with booking but the service was excellent. I love my stay there, they have great food great room service. As they say good things comes in small packages. No reception after 11pm but there is always a night guard who is always there for assistance. He is helpful! I love everyone at that hotel except one lady, I believe is the manager who kinda didn't want me to stay there. Though she was very professionally well behaved but somehow I got that feeling. I had to move out due to lack lack room extension. It has a small bar and seriously great food restaurant for a fraction of a price! I love my stay there and will definitely recommend friends and family to choose it, when going to adelaide. Worth the money spent and with impeccable top end service quality. I get the feeling that everyone in that hotel do whatever they do by heart and not for the sake. Except that manager. Also there is a gentleman at the reception who I believe is only man in the reception. He was just fantastic, he took my reservation before I left for Adelaide. His service is top class nothing less. He was helpful and very kinda with the service he provided. I really appreciate his generous help and his impeccable service. Maybe a little small, but compact and fitted with all necessities that travellers usually need. It's like a staying in a smaller version of a 5* hotels. It has a swimming pool though due to lack of time didn't get to enjoy a jump in the pool. They also have spa but also didn't get to enjoy it either. Have clean laundry. It's about $8 for wash and dry. Do not choose a room on level 1. Level 1 rooms are very close to laundry and also it's at the entrance of after midnight entry. Can be quite a distraction.

We had a very enjoyable stay at Royal Coach, the room was very nice, clean, good size, everything we were after for an overnight stay. We even had a late checkout of 11am - however, what is the point?? At 8am on a Sunday morning after attending a late wedding the night before, we were awoken by the housekeeping staff. They were out in the corridors - yelling down the corridors to one another about cleaning products, towel numbers and I think one of them even managed to drop a tray of cutlery or dishes. The noise was incredibly loud. My partner and I were then wide awake, gone was our sleep-in on a very rare weekend away for us, thus creating too rather disappointed and tired people.
The guests really dont need to hear the discussion between the housekeeping ladies of who gets paid how much on Sunday rates, who was called in and who was away. This was heard through the walls and door!!! Management should take it to task and remind these women just how loud they really are!!! Shhhh please.
We probably would stay there again, as it was nice and catered for all we needed, but I wouldnt do it for a relaxing time-out weekend.

We found the staff friendly, efficient, very obliging and the rooms were clean and well serviced. We would have enjoyed a longer stay but were only able to be there for 1 night. Close to city nice walk through lovely park.Definetly recommend to anyone wanting a great place to stay.
