Probably the cheapest viable place you could go and find a nice set up. Easy access to hiking in the Himalaya! Internet connection is ok and has probably improved since I was there. You can probably get by on 200$ a month if you are frugal and the climate is mild!

Or "splash out" and stay here: https://www.airbnb.co.uk/rooms/11315606?location=Pokhara%2C%...

probably still spending <500$ a month!
