Housing in Niamey

Hey everyone!

My name is Pau Arranz and I'm a Sociologist and Spanish teacher from Barcelona. My wife and I will move to Niamey next September and I am looking for a place to live. My wife will live in a NGO guesthouse but I'm not allowed to live with her or in the guesthouse.
So, I will stay in a hotel for the first weeks but it's my goal to find a guesthouse or a house with a room to rent, for instance. We will be living in Niamey for 4 months and living in a hotel isn't an exciting or affordable plan.
I'm starting this topic if any of you can give me some advice or even information about housing in Niamey. I know there are a lot of things that I will have to figure out once I'm in Niamey, but I would truly appreciate any information or help that you could give me (if you know of any guesthouse for expats, shared villas, etc)

Thank you very much in advance,
Pau
