A nice cosy studio. What makes it especially attractive is the amount of light through the big windows and the view of a little park and beautiful church outside.
The air conditioner is not fully functional (it has a hose that has to be manually placed out an open window, but there's no set up for blocking shut the rest of the window opening). Luckily, we didn't need it when we were there. Perhaps Driss could improve this point (or just be clear about it in the listing)?
In other respects, it's good value, and Driss is a very welcoming and pleasant host (fluent in English, as others have noted). The extra touches (bottle of wine left for us in the fridge, package of chocolates on the table, the personal recommendations of things to do in Paris) -- these things make all the difference. He deserves the "super host" designation (if he hasn't earned it already). Cheers!
