The Livebox modem has total 4 ports where 2 are used now. Guests can easily use the remaining unused 2 RJ45 ports for computers. The connection speed is about 600 mbps down link and 200 mbps up link with a CAT7 cable. Wifi maxes out at 123 mbps up,down link.
The chair and the desk by the window aren't really usable for serious office or professional work. You'd need to bring a 10cm==4inch monitor or laptop stand to increase the height. Overall a good choice. Everything is new and clean. I like the Schneider Electric switches and outlets. The bed sheets are warm. The guest service is very responsive and easy to work with.
