Abdel's place was perfect for us as we were attending a conference at the Paris Convention Centre - it was only a few minutes walk away. The place is clean, well-organized, comfortable beds, great shower and has the basics in the kitchen (we didn't cook so can't speak about that) - its very close to a grocery store and bakery, café's and the metro making it easy to get to other spots in Paris.
The apartment is small but was perfect for 2 of us. The air conditioning unit worked really well. Like others, we noticed a sewage type smell from time to time - we also noticed elsewhere in the neighbourhood - in the apartment itself it seemed pretty temporary and didn't really detract from our stay.
The shower is terrific - its a bath/shower combo - you have to step into a tub with quite high sides so that could be a problem if you have hip/knee issues. It was great for us as we like taking baths as well!
I would stay here again if I was at a conference at the convention centre! I also liked being in a pretty typical neighbourhood - found a little café close by run by a couple with a very cute baby and frequented by locals which I really liked. And the bakery close by has fabulous croissants, baguettes etc!
