Customs regulations.
Clean
The toilets are normal.
Shops are 1 km away (cheap taxi).
The customs clearance process is peculiar; documents for work are taken to the customs center in the city.
The staff is friendly. The bad thing is that you have to uncouple at night and leave for SVH. This prevents you from working according to the regime. It is also bad that there are no showers. It could even be done on a paid basis.
