Katia's apartment was very clean, beautifully fitted out and perfectly positioned between the Marais and the 1st arrondissement. It was spacious but there was little space to hang our clothes or put our luggage as all the storage was full. The kitchen was great to use and well stocked. The couch was super comfortable to collapse on to after a full day exploring the city.
Would recommend Katia's place to any of my friends. :)
