We stayed in Nathalie's apartment in June 2014. It was very convenient for us and we really liked the area. Nathalie was also very helpful and responsive... to the point where when we accidentally left behind a bag containing our passports, despite being out of the country she arranged to have someone come and help us back in! The apartment has a great view which makes up for the stairs, and has a really nice big lounge area. Large numbers may find the single bathroom an issue but we got by fine (there is a separate toilet so that helps).
