While your layout is an improvement it's still a tiny space to cram everything in, while your pictures show everything you need there's really no room to walk.
If you search enough, some places ( the executive residence #2 thru #4 ) offer minimum about 70sqm for 1 bedrooms, that's workable, good location and decent value IMO.
Some people don't like that it's off the baht bus route but for most long termers they have transport.
Just my opinion.
The slight older, but bigger footprints, are becoming more popular than the newer shoe boxes.
