We had an enjoyable stay at Guillaume's place at the end of February 2018.
The apartment is located in the vicinity of a number of metro stations and is quite easily reached by foot from the main city attractions. The area surrounding the Barbès-Rochechouart metro station wasn't the most welcoming or appealing. Other than that, the location was ideal for exploring the city.
There are plenty of shops and cafes in close proximity to the apartment. Montmartre, with its substantial collection of restaurants, boulangéries, crêperies and souvenir shops, is a short walk away.
The interior is typical of a cosy Parisian apartment, complete with a balcony and large windows that provided plenty of natural light.
The temperature in the apartment was perfect, except for on the Sunday. We later learned that it is usual for Guillaume to turn the heating down on that day as he is rarely in the apartment at that day. Guillaume quickly restored the apartment to its normal temperature when it was requested. However, you may want to bring warm socks or slippers as the floors are quite cold.
Although we did not get an opportunity to talk much with Guillaume due to the short and busy nature of our stay, any contact we had with him was pleasant. He offered great hospitality and was very helpful.
We would definitely recommend!
