We haven't met Enguerran personally, but Pierre, his friend, welcomed us in front of the building. He was very kind and helpful, it was a pleasure to meet him. The apartement was small, but nice, comfortable for those who's only for sightseeing in Paris and use the flat only for sleeping, then you have everything you need here. We even had a fan too, but it was very small. Even though we didn't use it, due to the great weather, on hot summer days, it would be a very weak solution, so I recommend getting a bigger one there. My only problem was the neighborhood. The noises from the street was very annoying. Twice a day a garbage truck came with huge noise, every minute some truck came and someone packed up something very loud, the people also talked loud there, there were great 'conversations' on the street even at night. All of these were very hard to tolerate with open windows, but it was bearable with closed ones. If you are a bad sleeper, maybe this is not your ideal place to stay.
Fortunately, I am a very good sleeper, my fiancé's not, but he had earplugs, so we could manage this situation, but it was not pleasant. Otherwise, we had a great time here, the flat was nice and comfy as I said, and we also had a nice guide waiting for us with maps and suggestions on public transport, markets, sights, bars etc.

One more thing: the supermarket, which is app. 5 minutes from the building, G20 has a very low stock from everything and we only found basic things like still water, orange juice etc. but it was also very limited. I'd suggest to use Franprix or Carrefour shops which are in the next street (Rue de Paradis, about 10 minutes by foot). It would be useful for others if it would be included in the guide you gave us.

Thank you again for having us and let us stay here :)
