I went to Paris for 3 nights and wanted a room that's quite central and has an en suite and this was perfect.
Mario and Camille responded to my messages promptly and in a friendly manner.
They provided me with directions, and plenty of information and recommendations about Paris and local area before arrival.
The room was clean, bed comfy and had a great shower. They provide basic toiletries and towels. It was very hot when I visited and I used the fan they provided in the room couple of times.
There are also maps and restaurant pamphlets available to give you ideas - very helpful.
There's a small separate fridge for guests and a coffee machine for your breakfast.
They also have a toddler but somehow you could barely hear her!
One thing some travellers should pay attention to is late check in. I didn't really mind as I only had a 2.5 hr journey via Eurostar that arrived to Gare du Nord which is only one stop away from nearest metro station, so I wasn't tired from my trip, but I imagine people who had a longer journey would like to shower, change and rest as soon as possible.
But you can come and drop off luggage until it's time to check in. They were also kind enough to let me check out later or leave my bag and come back for it later, as my train was in the early evening.
Overall I really enjoyed my stay and would come again. Thank you Mario and Camille!
