Pros+
The place is clean and very quiet. I like the view and also liked the slow pace of everything around. Also I wanted to explore the 9th, so the place is conveniently located.
You have a kitchen to cook - it keeps your costs low.
Cons-
There is no toilet - you have to go to the corridor.
The place is super small.
Don't recommend to for business travelers - you won't find iron for your shirts or washer/dryer.
