Hervé is a great host, replying fast and organising everything so it's perfect. He even came by for check-in and showed us everything himself. The flat is very nice and great for a big family or group of theatre improvisers like us :)...not suited if you're very noisy at night or want to party, because there is children sleeping in the apartment above. For us it was great, cause we needed a place to relax and recharge and we were often out for the evening.
Regarding light and technical amenities (kitchen, TV etc.) it's also top notch!
The flat is close to the Halles de Bocus and to the metro, but we actually walked everywhere. We were all women and we felt safe in this neighborhood and the bakeries and supermarkets close by cared for us with rosé and pains au chocolats :) All in all I can recommend it 100%!
