Hi are rooms 309/10 with a balcony at the front and which floor? are there fire alarms in the hotel? Thanks
Best to phone the hotel; I don't remember.
I can't imagine there are no fire alarms - that would be illegal.
There are fire alarms. Room has openable windows towards the Gare. No balcony worth the name.
