Have tested this out @ Hotel Formule 1 Gennevilliers ,Asnieres room for 3 @ £28.29 per night/per room and 78p per person breakfast. = £30.63 per night for 3 = £10.21 per head for 3.
Due to reviews,maybe better suited to youngsters/students/groups not ideal families.
This offer is for a breakfast, I think it's normally 4 euros. look for the yellow promo button @ hotel name,after choosing dates.
Rooms seem to be basic but clean,they seem to have sinks,but shared bathrooms, not bad reviews on Tripadvisor too.
