Accomodation in Windhoek for 1 night for 1 person on Saturday 3 March 2018

I am travelling from Cape Town to Uis in Namibia to meet some people and join them for a ride.

I am looking for cheap clean basic safe accomodation for myself in Windhoek for 1 night - Saturday 3 March 2018 - a bed and a safe parking for my bakkie with bike is all I require

Can anybody recommend a good spot ?

I will arrive late afternoon early evening after a 1500 km drive and will literally shower, eat and sleep before leaving early again on Sunday morning
