I stayed with a friend at Aurelie's for about 6 nights. The host has been very accommodating in terms of check in time (we were horribly late) and has been kind and available.
The place is on a busy street on an ethnic quarter; for people who are looking for a quiet night's sleep or that aren't used to the city, you might want to look somewhere else, though it's not that bad. The place is small but fits two people easily and is very well connected. Services: the tv set was a treat (if you want to watch movies) and the wifi worked very well but the cleanliness of the dishes and room could improve. Overall, I recommend the apartment for young people who are looking for a well connected place in Paris on a budget and who are not afraid of taking the metro everyday to go towards the city center (or anywhere else, for that matter)
