Hi Therese, thank you for the feedback!
With regards to the sea: it might get rough in low season, however, it is calm during high season and perfectly fine for swimming with kids.
Apologies, if it was not clear whom you should contact during your stay. While we are always ready to help and answer any questions, it is usually faster to call Chittra, the landlord and caretaker, to solve issues regarding the house. Thank you for pointing this out, will be more specific in the future.
