RE: Tipping House staff
In my past experience, the properties we've rented (from casita, condo, villa) all provide a helpful "manual" with information on what the owners recommend as far as restaurants, things to do in the area, and how to tip the house staff. We always give at least what is recommended (usually more). They do guide you on what to tip extra for meals cooked esp. if they do the shopping for you.
Sometimes we live no particular way, but our own!
