The location is convenient - 20 min to Bastille on foot, and Alexandre Dumas metro is just round the corner. Rue Charonne nearby is full of shops and restaurants.
The room was relatively clean, but the shower is moldy and not pleasant. There was no ventilator, and during the summer heatwaves the night temperature can stay at +33 Celsius, so it's not possible to sleep without the ventilator.
There was some noise from bathroom fan that could not be turned off.
The price was the main point for me, so my stay was tolerable, but the bathroom needs renovation.
