We did not meet Greg et Isa in person, but the moment we needed something Greg responded right away. Anyhow, everthing was clear and well described in Greg's indication!
The house is beautiful with nice littel details all over the place and nice littel terrace - we especially liked the quiete neigbourhood and still there are quite some restaurants in walking distance. Just a few stops (10) into the centre of Paris - whenever we go back to Paris we will stay at Greg's place again!
