Stayed 4 nights w a friend. Henley was easy to communicate with and was flexible with slightly earlier check-in time since my friend arrived before me. We only had one minor issue with the shower that I brought to her attention after we checked in, but she addressed my concern quickly and professionally. The apartment was just as pictured - clean, cozy, charming, and perfectly located on a picturesque street in Le Marais. Having an elevator was a big plus.
The neighborhood has tons of cute boutiques, restaurants, and bars for all tastes. We were lucky with perfect Spring weather and really enjoyed having the big beautiful French windows open and looking down at the street while enjoying a glass of wine. The terrace was also a nice added bonus.
The main bedroom is nice and comfortable with plenty of closet storage for hanging clothes, etc. My only minor complaint is that the pull-out bed for the couch in the living room isn't the most comfortable thing to sleep on, but we made due for a few nights. Since it was only 2 of us, we were perfectly comfortable during our stay.
All in all we had a great vacation and would certainly be back to stay at Henley's the next time we are in Paris. Would recommend for sure.
