I would just like to suggest a few small additions that could make the experience even easier and more enjoyable for future guests. A small mat in the kitchen area would be useful, as well as a fan in the bedroom with the single bed, as this room can get quite warm. When the door is closed, the air conditioning does not cool this smaller room very well.
It might also be helpful to provide a few basic cleaning products and something to help keep mosquitoes away.
These are only suggestions, as our stay was really wonderful and we had a very good experience. Thank you for everything!
