The apartment of Guillaume is gorgeous. Very cool place, clean, spacious and quite original in the design. The rented room is upstair in the attic and was perfect for a short stay. You can't get a better Paris vibe then this place. Very well situated, not far from the metro/tube and very safe neighbourhood. Sadly I couldn't spend much time with Guillaume, but he was very welcoming and it was easy to checked-in. Easy to find cool spot for a drink or to eat around.
I do hope to come back one day for a longer stay !
