The view! Oh my, the view. The pictures don't really do it justice, but it has probably one of the best views of the Eiffel tower in all of Paris. The location is good right next to the metro (although nearly everywhere in Paris is next to a metro stop), the apartment itself is OK -- seems as though it was designed to have two student rooms and was then converted into an AirBnB (i.e. both rooms have a fridge+sink+stove) which is fine, just a bit unusual. The shower is a bit annoying in that it's like a shower in a public bath, where you have to press the button every 30 seconds for the pressure to stay on, but it's not a big deal. The kitchen is supplied with only the most basics, so you probably won't prepare any dinners here, but it's fine for simple breakfast or lunch or making sandwiches, and there are so many good restaurants nearby anyway.
But let's be honest: you're looking at this place because you saw the photos of the view, and that view will not disappoint.
