This apartment is more than a place to crash, it's like living in a Parisian fairytale. I'm a New Yorker and was visiting Paris for the first time. My French friend recommended Saint Germain des Pres (this neighborhood) - it's an upscale area and Juliette's place was considerably more affordable than other options here. I'm incredibly glad I went with her place. The location is the best aspect. I'm big on strolling (NYC) and this apartment was situated perfectly within walking distance from so many of Paris' gems. The street is safe and serene. I'm a light sleeper and every night was perfectly quiet.
The room itself is TINY. Like perfect for a solo traveler (my case). Two people who can share space well would probably love it too. Anyone taller than 5'11" may feel a little cramped.
Also, I know a lot of reviews have mentioned and Juliette is very clear about the stairs. This apartment is on the 5th floor, no elevator, extremely narrow spiral staircase. Which in my experience was an added characteristic of the fairytale. I needed the exercise honestly. But don't be a jerk and complain about lugging your 50lb overpacked suitcase up. You've been warned.
Lastly, the decor of the apt sent me to another world. Juliette is an art student and has made the place her own with pictures and little touches of French flavor. I can't say enough about the vibe. It really made my first time in Paris all the more unforgettable.
Also Juliette is a sweet heart. Communicates with clarity and efficiency.
Enjoy your trip!
