Luxury HOTEL, very competent staff, speaking several languages including French too, but clean, humid, odorous, dilapidated establishment and especially room 618 where we could not sleep for 4 days because nightclub right next door and wall no soundproofing from 10 p.m. to 6 a.m. for the first night and 10 p.m. to 4 a.m. for the other days, hellish noise we could dance!
signaled in reception LA "not understand French"
Happy to come home to sleep in a non-luxurious house but sleep !!
To be sure: plasterboard with glass wool might do the trick ...
