Staying with Richard, Matt, Timmy and Marmalade is the one of the best experience I have ever had.
Everything about the place was exceptional, it was clean and stylish. Room itself was well equipped and very comfortable. I heard barely no street noise despite being facing onto a busy road.
Besides that this place is very easy to explore London via public transportation. There are 24 buses in just 2-3 min walk and five bus stops from london underground (bakerloo and northern line), which I can get into the central of london less than 30 mins.
Also they have two well behaved cats, Timmy and Marmalade.
