Sally and Mathias (& their cat Elvis) are the most wonderful hosts a traveller could ask for, and I absolutely enjoyed my stay with them!
The flat and my room were gorgeous, really cosy and - also very important - clean. The breakfast was rich and delicious, and you could just tell that both Sally and Mathias love to have guests at their home.
They also provided me with all kinds of information for public transportation which made it very easy for me to get around town (the nice quarter they live in and the short connections to central London with the bus and/or train are definitely another plus!).
Unfortunately I only stayed for two nights, but I will definitely have to come back to their place. I felt very welcome and like home :)
