Charlie and Annemarie's flat is an incredibly cozy, warm, and relaxing place to stay while visiting London (especially for work trips!). They made many recommendations in the area for me to go to for drinks, groceries, and just were very helpful in getting to the flat from the airport.
The flat is in a convenient location as well, right by several bus stops for public transit routes, and an easy pickup by cab/ride-sharing as well.
I would definitely recommend staying here if traveling through London and wish to have a very relaxing, but trendy stay.
