It’s not an apartment. It’s a place where you can sleep. Though the mattress is not really a mattress - very thin, and the bed-space is not enough for a normal/large person to stretch out. You can hear people of the next apartment talking - no noise insulation at all. Maybe that’s all normal for Paris - but compared to most other places on the planet it’s ridiculous. Only acceptable if you are willing to make compromises for 1 or 2 night.
Good location, though. Lots of bars, cafes, restaurants in walking distance. Public transport also very close.
Bring a hair dryer maybe. There is none. We didn’t meet the host.
