The appartment was as expected, really clean, a great location (next to the underground station, and with plenty of bus stops as well). We stayed 6 adults and 1 baby, and the appartment was big enough for us all. Even located in a noisy street, there was no noise in the bedrooms (at the back of the apartment), although the two who slept at the coach in the living room weren't so lucky. We rented a baby cot but there was no matress or fitting sheets for it, this would be something to improve. Also, there is still a bad smell in one of the bathrooms, as I rode in previous comments.
But the stay was great, and the service quick, we had some cuttlery missing and this was solved really fast by the office, great customer service and quick reply. I would really recommend this appartment to anyone, and of course stay here again if I return to London.
