Very friendly staffs that talked very good English. The staffs helped us a lot by showing the correct road when we were going around the Paris. The room was quite big (we stayed in 3 persons room) and we really love it. The en suite toilet was big too.
There should be free WIFI. The room was quite small. For 1 day stay is okay (especially if you are going to board Eurostar) but I won't recommend if you want to stay for more than 1 day.
Good place to stay. The staffs were friendly. Quite near with the Underground station. And yup, the WIFI on every floor is a plus!
