My wife and I had looked at the Siesta before departing for Grenada but we didn't book because we wanted to check it out when we arrived.
Impressed by what we saw, we booked room #1. There was a king sized bed, AC, TV, desk and coffee maker and some outdoor seating to relax at the end of the day.
We only meet one staff member, but she was friendly and helpful.
The best thing about The Siesta is its location. It's close to Grand Anse beach and some great restaurants at Le Marquis Plaza. You could probably walk to Morne Rouge but you'd be better off hopping on a taxi/bus.
