The location of the apartment is perfect. The tube is within walking distance. As is the Portobello road and a few nice breakfast spots.
The studio itself is located in a beautiful and calm neighbourhood. It is pretty small but you will find everything you need. It's not the cosiest apartment but I would still recommend staying there if you are looking for a base from where to explore London rather than spending your majority of the time inside.
Max and Billie were friendly and offered us to leave our luggage in there office after check out which was really convenient for us.
