We had a lovely stay at Lionel and Marc's. We really loved the neighborhood. Central location in Paris close to many metro stations with tons of great restaurants and pastry shops around. There's a grocery store just downstairs and another one down the block.
Marc and Lionel were great hosts too. Good communication and very accomodating. There's a welcome book they put together and we went to a few places they had suggested - all wonderful! The most thorough guidebook we've come across in all our airbnb stays. It was much appreciated.
