My wife and I just had 1 night at Siesta, not enough time to do a thorough assessment, but we found a few small touches we wanted to comment on, e.g. cable TV, wi-fi, clean and spacious room. We arrived on a Saturday afternoon following an 8-day sailing trip, and our luggage included a large bundle of dirty laundry. The hotel got it all washed and dried and returned to us that evening, at a price of about US$2 per pound. We also appreciated the small fridge in our room. (A microwave would have made a nice addition.) The air conditioner was effective and quiet, attributes we've not always found at budget hotels.
A fairly new restaurant on the premises (Le Papillon) serves breakfast and lunch all day, but is not open for dinner. Our only meal there was a breakfast of poached eggs and a callaloo quiche, both of which were excellent. I was very happy that my espresso was correctly made, bold and flavorful with a nice crema layer on top.
A short stroll from the hotel through a field and down a narrow lane leads to Grand Anse Beach near the south end and close to Umbrellas beach bar, which seems to be a favorite hangout of expats living nearby. The beach itself is a great place for barefoot jogging - smooth packed sand with only a slight pitch.
