Glastonbury is nice but being the sort of alternative place it is has it's fair of oddballs (people that walk around barefooted and hand out chemtrails leaflets and Piers Corbyn's mates). Can be relatively expensive in some of the snooty independent shops and cafes. Complications for commuting during flooding on the levels or during the festival week in the summer. The nearby town Street might be a cheaper option and has more amenities, in terms of supermarkets etc even has an outdoor pool used in the summer.
Wellington is nominally a town but only has about 15, 000 people so has a villagy feel about it.
You didn't say whether you were renting or buying but I had a look on Wellington and coincidentally found this.
Been inside when I had a fling with the owner. No on street parking immediately outside but quite nice inside and modern bathroom. Quite high ceilings for a cottage (I'm 6'1 and
can't remember ducking too much). Green parks nearby and woods and walking spots short drive away.
