Guillaume's apartment is great to stay in summer! although there's no air-conditioning the temperature is okay because of the small and lovely courtyard. There's no direct sunshine and during the night we left the bedroom door open and closed the shutters halfway.
The bed is perfect. Taking a shower in the bath was a bit of an experience, but it went well after all.
And it is really really quiet at night, unbelievable for an apartment in the center of Montmartre.
We didn't used the cooking facility - there a lot of nice restaurants and lots of take away options nearby.
The only thing I missed was a Nespresso machine (and my son missed a TV 🤫)
