We really wanted to like this place, and for the most part the cottage and our stay were fine and relaxing. There was something kind of off about it though.
We stayed in a 1 bedroom cottage with living room and kitchen, 1 bath. Although a little cramped, the layout was pretty good for us -- we were with our 5 year old and our infant son, and we were able to room with our son with the portable crib mostly in the closet of the bedroom and our daughter had the LR couch. The main point for us was to have some doors to close.
The chief problem was that the A/C unit in the living room was broken, working sporadically and very difficult to control. One night it got stuck on freezing, then our only option was to turn it all the way off, so our daughter was baking, and we had to open the door to the bedroom to give her a comfortable temperature. That of course made having a door to close beside the point. The owner Joyce's response to our complain was kind of weak, she really didn't go out of her way at all to do anything for us -- she sort of shrugged and said the A/C needed to be replaced, that she planned to do it when the season was slower. Umm, thanks, but where does that leave us?
The cottage as a whole was fine, pretty much clean, although there was a strange smell, kind of like urine mixed with strong cleanser?, when we first checked in. I got used to it and just assumed it was some kind of high-strength cleaner they had used before we got there. The pool was quite nice, and it was great to have nearly sole use of it (4 cottages seem to share it, and only 3 seemed to be occupied during our stay).
The small private deck attached to our unit was occupied by a maintenance/cleaning team doing some repairs the first day mid-morning, when we had hoped to sit outside while our son napped. It wasn't possible to do this because the employees were kind of all spread out in that space, although we made it clear we wanted to use it.
Cayo Hueso was not luxury, but the price you are paying is for the location, which is indeed great, just steps from Duval Street (and the quiet end), and for a relaxed and comfortable lodging. I can kind of see how the owner earned the comments about her being disorganized and a less-than-optimal manager in the two other negative reviews here. I'm mainly puzzled about how the reviews here tipped so starkly positive -- we are pretty laid back and don't need luxury in a place, but for some reason our experience here was less than stellar, and it seems like that wasn't matched in very many people's experiences of this place.
