Education professional seeking 5-6 months

I am a professional working in education as a senior leader. I am working in a school in Bridgwater from 23rd Feb - July. I am looking for somewhere to stay. My preference would be a tiny home/mobile home/glamping pod or annex with some privacy. I would happily consider a room in someone's house too. I love dogs and I would be out working every day. I only need accommodation Monday - Fridays (as I live in London) and may need to come on Sunday evenings. Would be helpful if I could leave some clothes at the property in the week but this is not essential. I will not be in the areas at the weekends.
Many thanks
