Small flat, but very well organized. It suitable for 4 people, but you almost has no place to sit together and drink tea .
Nice location. Very close to metro station and if you want to go by foot to the city center, Monmartr, Louvre, ... - al of them are in 30 minutes walk distance. Walk to "Moulen Rouge" took less than 10 minutes.
We had some issue with internal doors handles, but it was fixed in the same day when we asked.
Would recommend for companies/families till 4 people for short stay.
