The Belmar Complex is close to Macdonalds on the seafront at Limassol.
It houses the Sixt car hire offices at one side of the building and Europcar on the other corner.
Coming from the Old Town, it's on your left side just after the Cantone Restaurant and the turning up to the Atlantica Oasis hotel (you should see the Castle Apartments on your left side - set back off the roadside).
Coming from Ayios Tychonas / Larnaca direction and the Mediterannean Beach hotel, it's on your right side just past the funfair and Macdonalds.
It is possible to walk from the hotel but it will take a good 20 - 30 minutes possible and all depends on what time of year it is. If it's after mid July & before end of August - take the bus or a taxi!
