8.2/10 Very Good! (1,234 reviews)

The room was not entirely clean when we first arrived. The hotel lost water supply, the pool was clean, but not well maintained. The property is absolutely beautiful though!

9/10 Wonderful! (73 reviews)

Older buildings renovated on the cheap but good decorating and reasonably clean. Bed and bedding could be improved. Would be good for an extended stay. Staff very friendly and helpful. Close to old town but has free parking.
