After spending a week in hostels, Carole's place was like staying in a friend of a friend's. The house was quite near the metro station, and as a single woman I had no problem walking back to the building after 11pm. Paris' metro is well connected, so going to and fro between main attractions was no problem either.
Carole had everything ready in the room; with a large bottle of water, tea in the drawer, and a spare blanket. The room was a bit chilly but the blanket was more than enough for a good night's sleep. Oh, and two thick towels in the room made my day.
The bathroom is used together, but the room is very private, which was very nice for a tired traveller. The dog is VERY friendly, and still young (2016. 10), but as long as you keep the door shut there will be no problems.
Overall, I had a wonderful stay thanks to Carole. If I travel to Paris alone anyday, I would love to stay there again.
