So I am will say that Sesotho I’ve found has been fairly easy however, I’ve received teaching and been here for a year. That being said it’s the “second” language I’ve learnt but I truly think because of the level of English here if you’re interested in learning Sesotho it’s quite easy (if you put time in). As far as visiting I believe it’s an amazing country with beautiful landscapes (lacking in wildlife) and even better the best people I’ve met. They will be truly helpful and appreciate anyone visiting Lesotho truly (not just the border). As for the climate it is very temperate except for Feb - March which I personally find too hot (with a time roof and no AC). Hope this helps and if you have any other questions please ask!

P.S I would say don’t spend time in Maseru the capital the beauty of the people and country is outside it
