The stay was everything I could have wished for. Jean-Baptiste was super responsive and welcoming, both check-in and check-out went very smoothly. The place is awesome - a big, extremely clean appartment with an elevator which I was very thankful for considering my heavy luggage. Gabriel, the flatmate, was super nice - we had great talks and coexisted very peacefully when I worked.
A few steps from the building, there are rental bikes which are easy to use and pay for - it took me ten minutes to the place Bellecour.
Eating vegan, I cooked at home but there are quite some take-outs and restaurants and a bakery nearby and I frequented the Carrefour City right across the street. There was nothing I could have wished for and I'd come back anytime - je recommande vivement!
P.S.: Gabriel also speaks English fluently for those who have a hard time with French.
