The room is located in a very central apartment, in Holborn, near the British Museum. Ideal for a week visiting London and walking to other central parts of London (Soho, Oxford street, St Pancras, City...).
Gemma is an amazing hostess, easily available to answer my questions. Also the kitchen was available for use, which can help save some money if you prefer cooking your own meals instead of going to restaurants.
I will definitely book this room again next time I visit London on my own !
