Jean-Marie's place was an excellent place for me (a single traveller) for a month long stay, I imagine it would also work well for a couple. The space is one large open area but with some thoughtful touches/design for separations, there's not a lot of noise/visual separation between the room and the toilet so I'd suggest you know your partner well :)
There's everything I needed and more. Kitchen, Hob, Toaster Oven, Fridge, Washer, Shower, Toilet, Bed, Desk, Table, Wifi, etc.
They live in the same building/complex below you so if there were any problems I imagine they'd be taken care of immediately but I had no problems to report. There are a couple of neighbors cats that hang out in the main courtyard but they're friendly and like cats rather aloof unless they know you.
