Staying at Guillaume's is a true pleasure. As so many before me have said it, the pictures do not do this place justice. The view from the living room and front facing balcony are stunning. Such a beautiful skyline including Sacre Coeur and the Eiffel Tower!
The place is kept clean and check-in was very flexibel and comprehensive (done by Guillaume and his girlfriend). The kitchen is fully equipped with several supermarkets and restaurants within short walking distance. Two metro stations offer easy access to the rest of Paris. And if you want to stay indoors fast Wifi and cable TV are also available.
In short the perfect pied a terre and I will definitely be back!
