National square is well located near the train centrale about 10 min walking distance however if you have luggages, good luck crossing streets, sidewalk are dirty with dog*** i didnt have access to the room before 3 even when the room was available, i arrived around 10h30 and it was difficult to reach the management, we got the instruction for check in only 2 hours before 3pm, i would had appreciate to know where to put the luggage, to enter the building, you need 10 cents to take the elevator if it wasnt for a guy in the building lobby i would had to climbed 6 floors with luggage
