Me and my fiance had a great time in Eléonore's place. The location is just perfect, close to everything (1 min to Bastille, Marais, walking distance to Place des Voges, Île de la Cité, a few steps from a metro station, about 30 min walking from the Louvre Museum and so on).
She gave us a lot of nice recommendations on where to go and eat, her apartment is clean, sunny, very nice decorated and super comfortable for a couple. Internet worked fast, although the building is old and the entrance has a very strong musty smell.
