I've stayed in the Manor Apartment Hotel twice, and was impressed on both occasions.
While the hotel is very centrally located (5 minutes from Central Station and less than that to Queen Street Mall), it's very quiet at night. Both rooms I've stayed in have been large and comfortable with well-equipped kitchens. While my stays on both occasions have been short, the hotel seems very well set up for long stays, and it's notable that lots of people seemed to be cooking in their rooms (something which seems uncommon for apartment hotels). However, I wasn't a fan of the over-stuffed armchairs in the room I most recently stayed in: they were uncomfortable, as well as ugly. The continental breakfast is pretty good, with good quality fruit, bread and jam.
Overall, I enjoyed staying in this hotel, and will probably do so again on future visits to Brisbane.More
