Practical informations needed (Algiers)

Hello everybody,

I will be visiting Algeria for the first time for business and practical information before I land would highly appreciated.

How can I move around Algiers? how much taxis are for local 2/4 kms journey? Avrage prices for Restaurants in business area?

Is there a business area where most of big companies located or they are spread out?

Have you heard about those hotels
Hotel d'Hydra 58€
Hotel Suisse 52€
Grand Hotel Adghir 62€

If yes, what do you think of them and their location? Are they in the city centre or near the business area?

Best Regards,
