Malmaison is an old prison that has been converted into a hotel, which gives it a unique style.
The rooms are nice, relatively spacious with modern interiors.
Breakfast was nice, although the staff seemed to be arguing amongst themselves a bit much and they were relatively slow in taking orders for the cooked part of the breakfast.
The location was good, allowing us to walk into Oxford easily.
We stayed in Malmaison for two nights, during both nights we were quite warm. The air-conditioning or climate system or whatever they'd like to call it didn't really function well and because you can't open any windows the room heated up.
