The place is great!
Big and beautiful, full of cool books to take a look at (if you're not walking around Paris!). Also a lot of tips for Paris.
It's super clean, really comforable and quiet and has a small balcony and a lot of light, ideal to eat in on a lazy day (wine, a baguette and a balcony picnic for two <3). You can cook yourself (it has everything except an electric kettle)
Just remember that there are 5 floors of stairs to climb.
