I stayed at Antonia's place as an alternative to my usual hotel. Antonia is extremely supportive and helpful, her flat is in a quite location , very near to the Southbank and two minutes from the Northern Line.
A full English Breakfast and the complete use of the kitchen are to appreciate a lot. Though the bathroom wasn't in suite this was not a problem, I seemed to be the only one using it.
There are pro and con's towards staying in a hotel, that you may notice more if you are travelling for business than if on holiday
A good overall experience
