I stayed in Paris for just over a week on my own, and Ka's place was the perfect base for my adventures. The apartment is small but was more than enough room for me, and has a spacious bathroom with a lovely deep bath. Basic amenities like a fridge and microwave are available which was very useful. And the apartment is only up one flight of stairs, which was great with a heavy suitcase.
Ka's place is in a hip area with great shops, cafes and restaurants right outside the door - there's even an Australian-influenced cafe up the road for any Aussies craving a flat white ;). The metro stop is just around the corner, and Montmartre is just up the road, so it is very convenient for exploring Paris.
Ka is a lovely host and it was great to chat with her. She was very communicative and made sure I had everything I needed. I would definitely recommend her place to anyone visiting Paris!
