This is an adorable, quaint flat in a rather posh neighborhood, away from the hustle and bustle of the major tourist areas. There are lots of great cafes and bakeries nearby. Many different public transit options are available that are easy to get to...street parking can be rather difficult if you have a car.
The flat itself is lovely and modern, but if you are tall the bathroom may be a bit of a squeeze. The bed drops from the ceiling, and is actually quite cool and decent sized. The kitchen is modern and has the necessities like coffee maker, stove/oven, refrigerator, and accessories. The closet has decent space to hang clothes and unpack. There is only one small window, but plenty of lights! The lift to get you to the 5th floor is retro-style with the sliding doors, however there are still a few stretches of stairs, so if you have any issues with steps I would not recommend this flat for you. Carolina, who manages the property, is lovely and very helpful.
Overall I had a lovely stay and would not hesitate to stay there again when I come back to Paris. If you are lucky to stay in the flat after me, I left a few good beers in the fridge :)
