If you want to experience Paris like a Parisien(ne) then Katarina's place is perfect. A small self contained studio with a good facilities specification. The windows opening on to the plant-decorated balcony are very romantic. The tiny asenceur from the lobby to reach the 5th floor is charmingly eccentric (warning large people one at a time !!). With the windows open at night the sound from the cafes opposite the apartment were noticeable until 2 am. We are night owls so it added to the atmosphere for us. The south Pigalle , particularly Rue des Martyrs, is a very good location for exploring Paris. Great availability of local restaurants, supermarkets, boulangeries etc and good metro links.
Katarina had left adequate space in the fridge for our needs. If I had to describe the nature of this property it felt like a good friend, who had modern tastes, had lent you their place for the weekend. A purpose-designed holiday let this is not, it is someones normal home. We loved it and wouldbe delighted to return on a future occasion.
