I have stayed in many airbnbs before and Guillaume’s easily one of the best hosts. He is the most friendly, courteous and responsive. The rooms were absolutely great(perfect for 3 people) and they even had an amazing massage chair - a perfect way to relax after touring the city.
Guillaume was also flexible to allow me to store my luggage in the apartment after checkout as my flight was later in the night. The only downside is that there is no lift to the apartment; you will need to take the staircase. However the place and the host make up for the small setback :)
