At first I was a bit worried about communication. I had reached out to Lena a couple days before about a possible early check-in and didn't hear back until we landed at the airport. Fortunately, they were able to accommodate us and let us drop our luggages off, which we were extremely thankful for. As others had mentioned, the staircase is difficult to transport luggages and extremely dark. We also did question the cleanliness of some of the linen because my partner and I started to get itchy and develop a small rash.
Nonetheless, we would recommend to others because of how central it was to everything. It is a busy area, but felt safe knowing that there were 3 secure doors you needed to go through. The metro just outside of the door was extremely convenient and the location was a quick 20 min. walk to all the wonderful restaurants/shops at Le Marais.
