We stayed at Oliver's place on 21-25 of May and we highly recommend it. If you want to live in Monmartre and feel like home - this is the place.

Apartment: it has everything you can think of. Literally. You will find kitchen will all necessary items, comfortable sofa-bed, compact bathroom with shower, TV with plenty of channels, a reliable wifi, etc. Even the heating was working, so we could dry out our soaked clothes.
Bonus: we also enjoyed nice window view and beautiful flowers that Olivier grows on windowsills.

Location: very good. 7 min. walk to the nearest metro station and 3 min. walk to the famous Sacre Coeur where you can see panorama of the city. Nearest supermarket 'Leader price' is 10 min. walk.

Host: Olivier was helpful and answered all our questions. He surprised us with a welcome gift and provided an umbrella for the rainy days.
