This was an easy, hassle free experience. The apartment was easy to find and was better than we expected. We never got to meet Frederic but Katerine who met us to let us in was very nice and accommodating. There was an apartment below us doing renovations that started very early in the mornings and after mentioning to Karine she kindly contacted the neighbor and asked that they start working a bit later in the morning which I thought to be a kind gesture that we really appreciated.
Being that my husband and I were both sick the first couple days while we were in Paris, Frederic's place was the perfect home away from home to start our European holiday.
A couple of things to note- the climb to his apartment isn't for the faint of heart but is is certainly worth it. His bed also is very, very firm.
We loved everything about the experience and will look him up next time we're in Paris.
