Guillame's flat is amazing, top floor of the block gives a great view of the rooftops of the area and makes you feel very relaxed.
Guillame is an excellent host, his instructions are very clear and his personal handover/introduction to the flat meant no surprises.
The small balconies are amazing to look over the hustle and bustle and enjoy some Paris sunshine. The small kitchen is perfect and Guillames Coffee makers and Coffee are a great touch!
I would also recommend Guillames recommendation of the le Vin et Vert down the road. His local knowledge makes the stay so much easier :)
