Even if you normally live in a larger apartment and you arrive at Eric's flat with a thought of a tint little thing, please do not let yourself to be fooled. After a short while we felt great and cosy with everything around us. It's a great little studio with everything needed present, with a kitchenette and a little bathroom but both in a great size for two.
The location is fantastic, very close to La Bastille and Voltaire metro stations. By the way, it's worth to walk to Bastille for an excellent croissant/pain au chocolat/baguette or whatever else on the way in Maison Passos (https://goo.gl/maps/TSgybC6bSxCxj7sX7). Way better than anything in the area. It all sounds busy but one wouldn't believe how silent is the flat itself. The backyard orientation gives it a fantastic calm, however a better curtain would be useful in the kitchen.
Eric was very helpful, quick answering my messages and quick reacting to my suggestions or pleas.
To summarize, I very much advise this location for singles or couples that need calm in the middle of a busy city.
