I would definitely say it's shabbos friendly. I emailed the hotel that I was a sabbath observer and they put me on the second/third floor (the lowest floor with rooms). They were more than happy to accommodate, plus the concierge opened the room for us multiple times over shabbos when asked/hinted to. The only issue is that there's no manual doors to enter the hotel (all entrances are electronic/automatic), so you need to wait for someone to go in/out and follow. Ask your LOR.
Kosher breakfast is simple but solid. Each breakfast came with 3 delicious rolls, some type of fruit, spreads (cheese, nutella, jam, butter), and a small piece of cake. Sometimes lox or a bit of tuna was included. Non-cholov yisrael except for some of the cheese, if that applies. The lounge also has a plethora of kosher drinks (soda, beer, kosher chocolate) and fruit, which was helpful. If staying there, make sure to email the hotel with a few days notice so they can place the order. See attached pic.
