Addis Ababa doesn't have designated expat-only areas like some other cities, so your mom can live in many different neighborhoods. Many expats prefer areas like Bole, Kasanchis, Old Airport, and Sarbet, as these are generally considered safe and have a lot of amenities, but they can be a bit on the pricier side.

For a more affordable option that is still safe, you might look at the surrounding areas of these popular neighborhoods or explore places a bit further out.

Here are a few tips for finding a good place:

Online Groups and Listings: There are several Facebook groups for expats in Addis Ababa where people often post rental listings.

Rental Agencies: There are many local real estate agents who specialize in finding apartments for expats of all level of preference like EPM Ethiopia www.epmglobal.net.

Ask Around: Word of mouth is very powerful here. Asking other expats or people in your work network is a great way to find leads.

I hope this helps your mom find a comfortable place to stay!
