Halim's apartment was for the most part pretty basically furnished with a concrete floor. It has older furniture and appliances, including the range (stovetop worked however the oven was taped closed) and fans were relatively old (which during the heatwave in Paris didn't help much). We did find the air quality not great which may be improved if the windows could be opened. However, the bathrooms were quite good, and everything there worked well.
The location within Montmartre is good - close to the train line and can get to nice cafes pretty quickly. Although we did not have an issue, some people may not feel completely safe in the immediate vicinity of the apartment. However for the price and location this apartment is not a bad deal.
