In case of any misconceptions, this is not a conventional hotel, it is student accommodation for Canterbury Christchurch University. The rooms are clean and cater for basic needs with en-suite shower rooms, but don't expect a TV or phone in the room, or even a kettle - you need to walk along the corridor to the kitchen for that. The 'double' beds are also small doubles, and not particularly comfortable. Unfortunately at the time of our visit, a delay in completion of the key programming system meant that we had to be let back in to our block by a member of staff each time we went out; our key would only open our room door. Also some rowdy students (perhaps having just graduated) woke us up briefly during the night.
Having said all that, Petros Court is a very modern block close to the centre of Canterbury, and the room was spotlessly clean and reasonably priced, with 24 hour check-in facilities. Excellent base for anyone on a tight budget.
