Greetings from Indonesia!
Gillian's place is very nice. Located in urban area which youth needed are provided as well as bars, restaurant, and coffee shop.
In a walking distance, you will find a nearest Metro (less than 1 km) which connect you to the whole Paris area include zone 1-5 and buses.
From transportation, location and cost wise, Traveller should check out his place!
P.S : Gillian is very nice and able to help you give a lot of information that you needed during your journey. I'll be keen to stay in his place again when i have schedule to go to Paris.
