If you're looking for a welcoming place to stay while being in London with great hosts I can most definitely recommend Philip & Augusto.
They both make you feel like at home at there house, if you're traveling for the first time to London they got plenty of information & tips where to go & how to get there.
Even if you've been in London before, like me, they still got helpful tips for traveling around town from their place,which is very easy cause you got different options.
The house is very clean, stylish and homey, the bedroom in which I stayed offered more then enough space to relax/sleep, store your cloths and even if need an area where you could work on (desk) is provided.
Overall I was very happy with my stay and would definitely book again another stay in the future.
