There are times when things go off the rails for guests. This was one such occasion.
I understand you were away and your sister was left to pilot the ship for which she was unprepared.
Normally, after such an unfortunate series of events, there would be an acknowledgment, even an apology. Such was not the case in this instance. In a host that is something that cannot be overlooked.
1) No internet - intermittent access on day one - zero thereafter. Cost to me to purchase data package $80-
2) No hot water - "sorry - we have installed a new switch and I have to keep turning it on and off"
In a drought-stricken area advised to run water for a long time - to no avail
3) No air conditioning - in spite of alerts no effective air conditioning in the bedroom
4) No open doors - during a heatwave with no airconditioning told unceremoniously to "close the doors as the bugs get in"
5) No security - no locks on the bedroom door or on adjoining insecure door to adjoining laundry
6) No Suite - Made clear to me by your sister the adjoining living room was off-limits
7) No apology - host returns on my last day and no acknowledgment of all of the above AND
no apology
