Small room with a bed-couch for max. 2 persons. you can cook little things. there's a sink to wash yourself, internet, fridge, cooking plates, little oven, toaster ... well located at place de clichy/montmatre, next to two metro lines.
The equipment is not top top anymore but I'd make sure you would find clean sheets as well as a clean sink + toilets. Toilets are on the floor.
I would need a scan or picture of your ID or passport by email or fax for proceeding your request.
