Guy's place is truly great! Right next to subway station and short subway ride to most of the tourist areas. I didn't find much to do in the area around, but you can definitely walk to Monmartre- its close by. Also the bike station- Velib is right around the corner. The place is convenient, cozy and super stylish. Also safe, even coming back home at 12 am was not uncomfortable. I enjoyed talking to Guy's wife, who left me breakfast every single morning and was offering me hot tea when I got back from the city. Loved it
