We loved our stay in Francesca's apartment. We are a family of four: me, wife, and two boys ages 3 and 7 and we just spent there. We wanted some space to spread out and this place worked out great for us. There was plenty of space for us, the dining and living rooms upstairs were lovely, and we even had dinner in the garden a few times. It's an old (but well maintained) and charming place with a lot of character - something we explicitly prefer to a cookie-cutter type of new apartment.
Location is fantastic - two minutes from Central Park, five minutes to lots of restaurants on Amsterdam etc.
Francesca was very welcoming and left information and checked in during our stay so we felt well supported in the event we needed any help.
