This place is in a great location in Paris. While we did not have a lot of time to wander the streets of the Marais area, it seemed like a safe place to be. This place has a door with a code from the street, and that door is shared with other residents of the small courtyard. Then, there is a lock box with the key located inside, just beside the door. It feels very secure. As other reviewers have mentioned, the space is much smaller inside than the photos appear. Each bedroom has just enough space to walk, which leaves very little space for your luggage. If you have a carryon or something small, this should not be an issue. However, our group all had large rolling luggage, and we struggled to fit our bags in our room with us, although we did figure it out. I would not suggest any more than 6 people maximum, as the couch was super uncomfortable to sit on; I can't imagine that it would be very comfortable for sleeping. That main living area would be SUPER cramped if there were two people trying to sleep on that couch with their luggage out on the floor and other people trying to get through to the bathroom and kitchenette area. The bathrooms were nice; large showers and hot water tanks in each one. Be aware that one of the bedrooms does not have a door, just a tall curtain. This place is fairly affordable and in a nice location, so I recommend booking if your group's needs fall into what was described above. Just be aware of the cramped space!
