As everybody mentioned above, the view is stunning and seeing it day and night was magical! The apartment is small but very cozy. It's in the historical old building on a beautiful green street. The street is quite noisy, so earplugs might come in handy at night.
Trocadero square is just 10min walk, RER (train station) is just around the corner, subway is 4min walk, a big supermarket Carrefour Lamartine is 2min walk and of course there are countless cafes and restaurants nearby. And for those who are interested in the Covid-test on the way home, I recommend a laboratory just in the next building (next door to the supermarket) where everyone can have a test for free without an appointment.
The bed and sofas were comfortable. There was a stove, a small oven that could be used instead of the microwave if needed, a coffee machine, an electric kettle and all the other necessary utensils.
If you're not looking for a hotel-type experience but want to feel like a local while staying in Paris this is a place for you)
