Solo Trip - 45M - Support/help

Hi All

I am 45M looking to travel to Thailand for vacation, IN Feb 3rd week, probably for a month. Anyone know of any long term accommodation contact apart from aggregators please provide numbers.

No fixed schedule yet, around 16-19 Feb departure from Hyderabad, India to Bangkok, with plans to cover some beaches for a week in the end if possible. Am allergic to dust/pollution, is Bangkok gonna be bad for me( Sensitive due to Sinus surgeries in the past), if so please recommend a long term staycation option( Koh samui/Chiang mai?)

Any like minded people travelling during this time we can connect to see if we can tag along for the trip. I like reading books, am a decent conversationalist :) Prefer quite and calm over parties with a strong interest in exploring local culture, food and history, been to Bangkok couple of times for a short duration, so want to spend more time now to explore better this time.

I am trying to get my International driving permit before i leave in case cannot is a local alternative available for a fee?

Any other pointers please provide to make most of my trip. thanks in advance.
