We had nice stay at Alex's place. It wasn't fancy, but it was functional. It was also able to accommodate our group of six, which can be a challenge to find, and the apartment was large enough that we weren't tripping over one another. It was good to have a second bathroom sink in the WC as well. We fortunately missed a heat wave that had just come through, but it was still hot in the apartment at night. It would have been more tolerable with some additional fans and lighter bedding, so just keep that in mind if you are coming in the summer as I would think Alex would have helped with that had we thought to ask. A few of the beds are best for kids or short adults as well. Paris accommodation is expensive, so this represented good overall value relative to other options.
