Yacine's flat was very nice, and a good size for three people - we might even have been able to squeeze in four. It was pleasant and clean, the kitchen and shower (like a waterfall!) were great. Yacine was very friendly and willing to speak in English if needed. He provided all the info and instructions we needed which was very helpful.
The flat was well-placed - just outside the centre of Paris, and very close to a metro stop that would get you to la tour eiffel etc. in 10-15 minutes.
