We stayed here twice, for one week and then for two weeks. Throughout the duration of our stay Maria was considerate and helpful to us as guests. The house itself is in a great location for access to the centre of London as well as being a nice place to stay. It's a short walk away from Hampstead heath which is really nice and there's plenty to do nearby. The room is small and simple which is all you really need for a short stay in London.
Would highly recommend
