To rate a city, we have to ask in comparison to what? As this is an expat forum it should be compared to perhaps the city of origin for the expat, in my case London, UK. Additionally shouldn't we ask the budget of the comparison maker? Given enough budget wherever you are, you can make a facsimile of your favourite environment.
I've been to Addis several times and have spent quite a bit of time there, and I'm considering some kind of move, so I think I can understand the environment.
Lets be honest even new invigorated Addis is a train wreck compared to european cities. It has a gdp growth rate of 8 or 9% but lets remember its from a base of f***-all, relatively speaking.
Hospitals, schools, hotels and every institution from customs to road building is in a different world from what an expat may be used to. If you're a UN employee if you're ill you're airlifted to Kenya... says a lot. There are 4 or 5 "international" hotels. All the rest are spectacularly variable in their service. More recently it seems a lot of people specially those who have ferengi contact have gained rudimentary english skills, which goes some way to them explaining why they can't do x or y run out of z, don't have that in Ethiopia etc....
Aggressive begging, poor, ill people not getting healthcare, expiring on the street... being stared at like you've landed from another planet... crushing poverty, if you can't deal with this on a daily, (hourly?) basis, again Addis is not for you. If you can't deal with people getting in your face with their personal stuff then its a bad choice, if you haven't got any understanding or empathy of why they're like that then you shouldn't be considering a move to Addis. People are people and if you think expat life is living like a king whilst surrounded by beggars is uplifting then I would recommend you not go. Maybe book a therapist...
But that's not why anyone should move to addis... its not some undiscovered paradise just ripe for westerners to parachute in.
But... if you want a vibrant exciting (but dangerous....) city maybe its for you. If you want to participate in the development of a developing country then maybe its for you. If you want to help build the schools, hospitals, housing etc then book your flight, because its the right city to do it in. A true businessman with his heart in the right place could make some inroads, given the extreme demands for... everything... That means taking some risks, investing your own coin. Meeting the bureaucracy head on. I think Ethiopia is ranked the millionth best place to do business or similar. :
The food is unsophisticated in the extreme. The markets and shopping are pitiful compared to europe. But is that why an ex pat would go to Addis? You want a top western lifestyle go to a top western city. Simple! You want a genuine top western lifestyle for peanuts then .... I can't help you. A BMW costs the same wherever you are... except in Addis its got a 150% tax on it. Anything made in Ethopia is dirt cheap (and usually at the budget end of the market if you know what I mean). Anything made outside Ethiopia (thats everything your current lifestyle consists of if you haven't yet moved...) is taxed to the hilt. So disabuse yourself of champagne lifestyle beer money fantasies if you have them. (Champagne? Not likely)
Wait - exception to the rule - the coffee is brilliant, no question. Although the hygiene of the establishment serving it may be brought into question.
If you want a specific lifestyle with specific foodstuffs, living accommodation and western trinkets (electronics, internet etc etc) then the only way you can guarantee it is if you import it yourself, seal yourself in a little western bubble (see the embassies and wealthy expats for examples...). But that takes $$$$.
If you want to get on with a regular salary you'll have to take the knocks that one of the worlds poorest countries brings. I'd also say you need to learn Amharic asap, difficult though it may be.
Personally I'd struggle without a full english breakfast on a weekend. Thing is i've no idea where I'd get the bacon..... at least for less than a small fortune. If those are the kind of details you can't live without then Addis isn't for you.
On the other hand if you can adapt to take pleasure from the local compromises then its a great city. A bottle of cheap and nasty red (sorry Habeshers... but Axum and the other one is alcoholic ribena) is about 60birr, a beer can be 15birr. A cheeseburger is cheap... and usually quite grim.
The question of how does it rate from 0 to 10 depends entirely on what you;re comparing it to, and what lifestyle you think you you will achieve.
On a scale of 0 to 10 how does it compare to living on a lawyers salary in New York? or living on a manual workers salary in London? Those are much better qualified questions in my mind.
Still a cold beer in the Face of Addis restaurant (not Top View, because it hasn't got a view any more, which reminds me about rampant development versus almost complete lack of planning....) is a nice way to end the day!! One day I may move there for few years... try to rev up my mind numbing western existence.
