Thanks again Kasia.
As said, we really enjoyed our stay!
The house is exactly as described, absolutely no suprise.
Generally speaking the house is very comfortable, very quiet, very well equiped (kitchen, bathroom, etc), all super clean. We really felt at home with our 2 children. We also really liked the area, very well communicated (5 min walk from Parsons Green and then you're in the center of London in 15/20 min with the district line), with good shops to buy food at walking distance from the house (5 min). Great communication, Kasia's responses were always very quick and very clear, she gave us plenty of advice, really appreciated.
We definitely recommend and we'll certainly come back.
thanks again!
