Great place in a great location. Perfect for one or two travellers, but would be a little small for more. A very short walk from Trocadero, from where you have a great view of the Eiffel Tower. There is also a supermarket right under the building, and a couple of restaurants in walking distance.
Alex was very helpful, staying till late without a complaint, when we got delayed for the check-in. He was also very welcoming and gave us tips for going around Paris.
