Booked a 15 days reservation with Diamond Palace through Agoda. They lied about the room (I booked a deluxe and got a basic room). Website said cancellation is possible and refundable. Wanted to cancel after my first night and both the hotel and Agoda wouldnt do it.
Word of advice for ANYONE traveling. Do not book with Agoda and do not make long reservations like I did. Book 1 or 2 days max to see how the hotel is and where it is located. In Phnom Penh Cambodia there are plenty of hotels to choose from and no need to reserve in advance. Its rare that a hotel is booked solid and even if it is, it is easy to find another one.
And do not stay at Diamond Palace, it is a nice hotel but it is far from any good/cheap restaurants and far from any attractions. Get a hotel around riverside they are fairly priced.
