We booked an upgraded kind bed room 5 months in advance as my brother had a wedding at the hotel but when we got there I was shocked to see that the king bed was 2 single beds making 1 bed and was the most uncomfortable bed we've ever slept on. The next morning we complained to the manager by the name of Sasha. Her response was that the hotel was fully booked and we can only be moved into a standard room as that is how their king beds are. I explained that my family who also had similar rooms booked had double beds and not 2 singles pushed together. She was adamant even though I showed her images on the hotel's website that does not show 2 beds making 1.
Overall, the worst sleep ever and very unprofessional manager which made our stay at the hotel terrible. Will not be staying there again or recomend to anyone.
