Dakar

I've done about a month in Dakar - a lot has changed since the previous reviews. My sense here is that things here are on the upswing - but for a nomad it's a place with strong pros and strong cons.
The pros first: the vibes are generally good. Locals are friendly and kind, and the cultural life here is interesting and vibrant. Local food is really good. It's safe enough to walk around at night, and if you're on the BRT the local public transit is great. People are very active and there are loads of surfers if that's your thing. It's not the most techie place, but things are coming along - with the Wave app digital payments are accepted almost everywhere. The economy has been strong the past few years and a lot of new apartment complexes are coming up, so the quality of housing available is probably best in West Africa.
The cons: you're still in West Africa, which means the usual West Africa nonsense - things don't work and everything is too expensive. Supermarkets mostly have a limited selection of imported French products. I couldn't find a properly functional restaurant delivery app despite lots of ads for them (Club Tiossane for delivery groceries worked well, though). Hardly anyone speaks good English and even French speakers struggle to make real friends with locals.
But the real deal-breaker is the cost. The CFA franc is pegged to the euro (thanks France), so it's wildly overvalued and everything here is way too expensive for the quality. COL is comparable to a 2nd-tier American or European city - not worth it. If you really want to do West Africa, this might be the best place for a nomad, but on a global scale it's not competitive despite getting better. Come back if the government decides to pull out of the CFA arrangement and launch their own currency (there is a definite push for this).
