I'm sorry you didn't enjoy your experience. The volunteer position is clearly explained as cleaning, and we are in the tropics, so hot and dirty is kind of unavoidable. I understand that your medical condition is aggravated by the heat, which is something you should definitely take in to consideration and inquire about in advance if going to any other volunteer spot that is in a warm climate- our hottest months here are August and September.
When we're in slow season, deep cleaning empty rooms is standard- dust accumulates quickly here, and we need to make sure rooms are always ready for any last minute reservations. There's not a need for multiple volunteers when it's quiet, but volunteers are definitely welcome to socialize with hostel guests. We are located in Sandy Bay, which is mainly residential, with some tourism businesses mixed in (botanical gardens, dolphins, a few dive shops, restaurants etc). To me, a great part of volunteering is getting immersed in the local community, not just being around other travelers, and Sandy Bay is a good spot to get to know locals.
