I came here on a working trip and it worked out very well. The studio itself is small and comfortable, with a good desk to work at and solid, reliable wifi. The balcony looks over the street and is great if you want to stop working for a coffee or sit with a beer at the end of the day. The district is fascinating. It shows as a blank on the tourist map, but it's a tight grid of old streets with a lot of Parisian architecture, old cafeterias (the St Moritz on the corner is perfect for breakfast, with good coffee and quiet jazz) and antiquarian bookstores (there's one with a dog and one with three cats, take your pick). If your interests are literary, Borges lived just around the corner.
