We visited London for a week recently from the States and needed someone to take care of our 6 year old daughter during the day - take her around London to museums, parks etc. as well as engage and play with her. Mercy did all that and more! She worked with us on a suitable itinerary, took great initiative by suggesting other activities and during the course of the week kept us informed, took pictures etc.
Mercy is trustworthy, punctual, extremely professional and took great care of our daughter. Would highly recommend her!
