The overall quality is just ok. The room size is good, beds are not so comfortable, I found the bunk bed too high for my kids and the room layout could be better. The location of hotel is good to go walking to all Sentosa main attractions, this is the highlight!
The breakfast is the bad news: they serve in another hotel besides, the Hard Rock. Always crowded, few options, the taste and quality is "kinda sorta". Also despite we had paid breakfast in our reservation, they charged the kids (talked only adults were included, but this was never clear in the reservation, where says just 4 adults, 2 kids, breakfast included) and the price is quite high for the quality they offer.
I would look more carefully for other options, for sure you can find a better hotel in the area

The only positive thing would be the location, you are walking distance from a lot of the main attractions and the staff where very helpful.
No room service
Pool is ok but small and no bars, so there is no where to eat or drink at the hotel.
Rooms weren’t very clean
We had water dripping through a light fitting, the hotel hasn’t been well maintained.
It was advertised as getting passes to Universal but didn’t get any.
I would recommend staying elsewhere pay a bit extra and get a nice hotel.
