Juliette's studio is perfectly located in a quiet street next to Saint-Germain Blvd. A nice view is a bonus, I really enjoyed it! The room didn't seem tiny for me, but the shower might be too small for a tall (big) person.
Mind the stairs. If your luggage exceeds cabin size, you'll have to carry it either in front of you or behind, the 75 stairs are narrow. I didn't use the kitchenette or heating.
Juliette is a perfect host, very helpful and responsive. Though we didn't meet, I always felt her support. Thank you, Juliette, for your hospitality!
