Communication with Colette was very easy and she was very flexible with our late arrival. The apartment is really great and in an amazing location, extremely close to Sacre Coeur and in the centre of Montmarte. It's worth knowing that the shower is over a bath rather than separate. The only downside is that the sofa bed was extremely uncomfortable, but Colette provided plenty of additional blankets that I used to pad it up a bit. If definitely recommend this apartment for a break in Paris. Be warned though, it's up a lot of hills so wear sensible shoes!!
