Hardware (villa itself, lobby etc) was very nice and still very new. It was very pleasant to be staying in the villa. Suggest to change hair dryer to Dyson please. Service - Could be improved. Hardly the standard you'd expect from Raffles and at this price point. Butler - Nice young guy but attitude unfort, was gen Z. I had a t-shirt to do laundry on, asked him for the laundry rate, and he told me to check the paper in the laundry bag... Villa snacks - Complimentary daily refill never happened until i requested for it. Housekeeping/ Security - Poor. Asked housekeeping to make up the villa when i went out to lunch. Came back to a big shock. Housekeeping had finished making up the villa but left the main door wide open. Anyone could have entered the villa and stolen our things! Very bad. Buggy Service - only 2 buggy drivers were on duty on a busy saturday, one guy's attitude was not good, think overworked... please hire more staff.. Lobby Doorman - Excellent attitude, pleasant gentlemen Breakfast not included in our booking. At this price point, perhaps hotel can consider including breakfast for 2 pax into the bookings.
