The staff was incredibly kind and helpful. This place was exactly what I needed it to be; it was within my budget, kept me close to the city center, has an elevator for ease with luggage, and has air conditioning which very much came in handy since I visited during a heat wave.
With that said my nit picking comments are the room (I stayed in a Classic Double) was small - this was fine for me as a solo traveler but I wouldn't recommended it for 2 people. Lastly, while overall the hotel felt clean you could tell and see that some harder to reach places (think corners of the showers, etc) are due for a good deep cleaning.
Overall, if you are a solo traveler and you would like to stay close to the Eiffel Tower then I would recommend this hotel.
