The travel rules have not changed a lot, but you will need to get the best perosn to advice you fully on how to get here as a bussinessman, i hope you do get that.
I would like to help in the area of accomodation.
there are various places of accomodation in the city , you may choose from hostels to hotels.
please let us jknow what kind of accomodation you would like, if you need a taxi to travel aroung and if you may need some one to help you around for the first few days in the city.
all the best
