Great location. Lovely apartment. A bit small, but it's the Marais.
The cafe downstairs is a genuine find. Great coffee, fresh food, genuinely friendly service and very healthy.
The stairs up to the bedroom was as small as others had pointed out, so no surprises.
The only small point is the light switches are a strange up/down sequence for dimming/on/off (more complex than it sounds), which did create challenges. But the management were very helpful in advising on how to navigate this.
