The apartment is just perfect (in my opinion), next to west Kensington station (on district tube line) where you can come easily from the airport and reach downtown just in about 15-20 min by subway. The house is spotless, the room I stayed had a good and comfortable bed (I slept like a baby), the kitchen is fully equipped with fridge, microwave, stove and oven (except for a cork screwer/bottle opener, that gave me a little work to open my beer bottles) and it's all super clean. The bedroom is locked and you get the bedroom's and the apartment's keys, so no problem in arriving late, or any time you want at night.
Amira was lovely on my check in, so polite and friendly. During my staying she promptly answered all my questions. She also kept my luggage after my check out, due to my flight hour.
Thanks a lot!
