We stayed at Sally and Mathias's flat with friends over a weekend and found the flat to be in a great location to catch up and a base to visit London. They have both been friendly and accessible through the whole process and made the arrangements very easy. Key pick up and parking worked fine and hassle free. The flat was as expected and roomy for two couples. Breakfast, tea and coffee was left in the fridge for us to use and made it very homely. I would recommend the flat as a place to stay if you are in London. We would use the flat again
