Is it a palatial Hausmannian apartment with views of the Eiffel Tower? No! But is is a great little home base in a good neighborhood with all the stuff you need? Emphatically yes!
I stayed here for a week in July (beware - no AC, but a powerful little fan!) and made great use of the coffee maker and washing machine. It's located pretty close to the Oberkampf stop for the 5 train, and very close the Parmentier stop on the 3 train, if you're planning to use the metro to travel around the city. The best part about this apartment is the hosts: Nora & Nadir are really excellent, and they met me to show me how to use everything on the 1st night - crucial when learning how to use French washing machines :) I really appreciate their thoughtfulness.
Admittedly, the construction on the building was kind of rough a couple of mornings, but that's temporary!
