I can't fault this stay.
In terms of check-in, there seemed to be a group of people to communicate with so someone was always available within around 30 minutes of contacting. I was apprehensive about the location having never been there before but as soon as I arrived, it was a beautiful area and the apartment itself was clean, easily accessible and close to the underground. Going for a morning run by the Thames was really nice.
There's also a Tesco Express open till 11pm nearby, just along from the Underground, so again, anything you need, no problem.
Flawless.
