My travel companion lives his life in hotels and in transit due to his profession and I heared him say the words "Let's go home." during our stay in Paris, referring to this apartment.
I loved the aesthetic; it's small, it's coasy - but still modern and super functional.
The location worked well for our trips. You can walk to the next metro/train station/taxi stand within a few minutes.
If you really, really hate stairs, maybe don't rent this apartment. But then you'll miss out - so maybe just get over yourself and climb some stairs.
