I had a great stay with my two children at Leo's flat. We stayed for several weeks and felt at home! The area is handy when it comes to public transports and only a short walk from cool spots like the Canal / Esplanade Pajol and many more.
You are also very close to the Indian quarter which has fantastic restaurants!
The flat is exactly as described and very big for Paris. The beds are indeed comfortable and the kitchen and living room well equipped for any travelers to stay.
Leo was a great host, easy to communicate with and took on board our requests / suggestions.
He also provides with very handy recommendations for places to eat nearby which saved us time and hassle.
The only downside perhaps is that it can be quite noisy in the apartment and the area is very busy but if one isn't a light sleeper that will not be an issue.
Overall a fantastic experience and I would 100% recommend this place and its super host!
