As Guillaume wasn't there at the time his flatmate Sara prepared everything for us. She was really welcoming and helpful. The flat is a really sweet one and it was very clean. The location is fine as there is a bus stop nearby and the canal is around the corner. Just maybe if you need it really quite and calm (which should be hard in London) the room could be a bit loud for you, as it is headed towards the street. It was no problem for us. Great stay!
