Karim's place is in a very good location. It is close to all sorts of cafes and restaurants, as well as it is close public transportation. Best of all, it is only 15-20 mins walk to the Eiffel Tower.
Although it is small, it is comfortable enough for one to two persons. Karim was very accommodating and helpful. He helped me with the recommendations of his favourite dinning place and a place for currency exchange prior to my arrival.
All in all, I'd really recommend this place if you're here for a stay and have +1 guest. It's comfortable and convenient. Karim was a good host.
