 "A good-value hotel with large rooms with either a large bathroom or (cheaper) just a shower. There’s also a decent bar."

 "Owned by the same family as the nearby Hôtel Guynemer, this is a rare budget option in this area of the city centre with basic but large, airy rooms, some en suite." 
 "Cheap and clean and offers rooms either sharing communal facilities or with private bathrooms. Rooms facing inwards are quieter but a bit darker. Good value."
