I LOVE Montmartre!
Phillipe was an amazing host. The flat is so cute and quaint on a very lovely street in Montmartre. It's in a great location close to the Metro and bus stops. There are a plethora of cafes, restaurants, shops, markets and pharmacies within walking distance. The neighborhood is very safe and the flat is well secured. I highly recommend a stay at this location.
PS - I hope you like hills! Paris is filled with them. Great workout :-)
