The hotel staff was lovely and very welcoming. The property was extremely clean and well maintained, and the atmosphere made me feel like I was staying at a resort. The bedroom was spacious and very comfortable, which made the stay even more enjoyable. My only concern was the lack of storage space in the room. There was no closet or drawers available to store clothes, which made it a little inconvenient during the stay. Overall, it was a great experience and I would definitely consider staying there again.
