It was my second stay at Sandra's place and it was amazing again. The room is very clean and got everything you may need. Small kitchenette with fridge, microwave and kettle are very convenient, the basics like tea/coffee/milk are there and also croissants that Sandra provides for the breakfast(jam, butter, orange juice are there too).
The location is lovely, but I may be biased, as Kew is my favorite part of London. Nice running/cycle trail along the river Thames, Kew Gardens, nice sightseeing - Hamport Court, Ham House; good connection to the city center and Heathrow airport.
And also the cat, Hendrix is very cuddly:)
