Fantastic location, close to key tourist spots such as St Paul's, Trafalgar Square, Big Ben, the London Eye and Tower Bridge, plus underground stations.
Well suited to a couple, any more guests would sleep on a fold out couch which isn't very comfortable. In addition, there is no heating in the bedroom, only the lounge - which can warm the entire apartment if all doors are left open.
Refreshments aren't provided (i.e. Tea and Coffee), and limited toilet paper is provided - you may need to provide your own!
Communication from Host was excellent and efficient.
