Not the Hilton I was expecting, rooms are not five star as advertised bathroom is not very clean, shower curtain is very smelly, shower just about worked. Bar staffs are very miserable were not willing to serve us until we complained. We overlooked all of that because we were mostly out and about and only came to the hotel to sleep and eat at the buffet restaurant.
What really disappointed us was that, at the time of booking we were given a complimentary voucher to the two of the a la carte restaurant so we thought we will give them a try on our last day in Sharm when we went eat in the restaurants the waiters from both of the restaurant said "we have no table" even though the restaurants were virtually empty. So we told them how can they have no table when the restaurant only has 4 customers. I don't know if it was race related or not the strange thing is they asked us when are we leaving, as it was our last day we told them "flowing day", on our response they further confirmed they have no table so we had to make some noise to get a table. Later on we found out we needed to book the table. Would have been nice to tell us at time offering the voucher or even have a sign at the entrance of the restaurant saying pre booking only.
