Lal's place is a small one, but it has all necessary amenities (even including a washing machine, miraculously fitted into a tiny toilet cabin) and is well kept and clean. Sofa/bed is reasonably comfy, and kitchenette with a small fridge comes handy. I'd say the "dedicated workplace" part is a bit of an overstatement - a small table and a folding chair don't really make up a good comfy workplace, but to be honest I've almost never seen a good one in hotels or airbnb apartments anyway, even if advertised as such. Location is ~5min from a metro station (no major attractions nearby, except Montmartre, so taking a metro is usually necessary), the neighbourhood seems a bit chaotic but safe. As in many older Parisian buildings, access is only by stairs (might be an inconvenience if you have heavy luggage); window faces inner yard so it's quiet. The host lives next door, which is very helpful.
