Very nice stay, but the hotel seems at bit used. Maybe it is due to many visitors, but when I book 5 star hotels, I expect everything to be at the high end of the scale.
When at the pool, it should be forbidden to use phones, and especially to use phones for facetime. Not the hotel to blame for this, but pure and simple ethic rules for guest to apply. Maybe the hotel could put up signs, that use of phones is not allowed at the pool.
