I stayed at this apartment for a long weekend, working remotely on the first day, and sightseeing for the rest of the time.
The pros: the location can’t be faulted. This is walkable to EVERYWHERE. The Eiffel Tower is particularly close, but it’s also easy to get to the Louvre, Arc de Triomphe, Champs-Elysée etc. the apartment was very clean and despite being very small, was very well-appointed.
The cons: the major issue with this apartment is that it overlooks an internal courtyard. This means it is very dark, which wasn’t very enjoyable when I spent my first day working there. The apartment is also incredibly hot. While it was only around 20 degrees outside, the apartment was very stuffy. The window is essentially a door onto the internal courtyard, and given it is on the bottom floor, as a woman travelling alone, I did not feel safe opening it as someone could have walked straight in. Probably not such an issue in winter but in the summer it made sleeping quite difficult. However there is a fan provided and it is pretty powerful which definitely helps.
