If by 'pods' you mean things like this, then yes, I have stayed in them a few times. They are a little bit like sheds with sleeping platforms, a light bulb and, if you are lucky, a small electric heater.
I find them to be really cosy and welcoming, especially after a long day when I can't be bothered to put up a tent.
I have only ever shared one with people I know so it might be diferent experience if you share with strangers as they don't have much personal space.
