Visiting Kathmandu July 7-29

Hello all from Canada!

I am looking for somewhere to stay In Kathmandu from July Protected content (depending on flights). I will be assisting at the Koseli school in Tinkune, and would like to find somewhere close enough to walk to, or at least get to easily/cheaply.

Does anyone have any recommendations? I have been looking at hostels but am unsure which are reputable/ reliable.

I am a 34 year old female, not loud, non smoker but easy going.

Thanks for any help!
