The room was smaller than it appeared in the website photos, which was a bit disappointing. Although it had both a radiator and an air conditioner, neither worked properly during our stay.
The room phone was also faulty, it kept making a loud noise throughout the night, preventing us from sleeping. We ended up disconnecting it from the network the next day to stop the noise.
Additionally, there was no shower gel provided in the bathroom, so make sure to bring your own toiletries.
We stayed on the 3rd floor, and the stairs were very narrow with no lift available. If you have large luggage, I strongly recommend asking for a room on the ground floor, as carrying bags up can be difficult and even risky.
Overall, the location was perfect with 15min walking distance from Eiffel Tower
