You can't beat the location of this apartment. 5 minute walk to Place Vendome with many cute cafes and shopping in 1 arr. I would suggest to bring your own towels and pillow. Bath towel was a bit raggedy and the pillow was not the comfiest. Taking the elevator to the 4th floor and then walking up one more flight of stairs was actually favorable to me since that caused less foot traffic. This is a studio apartment that is very small, so I would say 2 person max. The bathroom is very tight, so if you're tall it could be uncomfortable.
The only big trouble I had was that the key would stick and I was unable to open the door for 5 minutes one time. Some times it would open right away, but became an annoyance when it didn't.
Also, there are no bathroom provisions like toilet paper etc. This isn't stated, so just make sure to bring your own before checking in!
All in all, it served my purpose of my trip! I wasn't there too much during the day, but it was nice to have the balcony when I was! 4 stars!
