Hotel Petka is just across the road form the ferry terminal and it is open all year round. 3 star and clean, nothing special but fine for a couple of nights or so.

try hotel lapad which is just across the water from Gruz, where the ferry and the bus station operate from

there is a little taxi boat that will take you across for a few cents - it leaves from right outside lapad and goes over and back from 7 a.m. to noon every day. (not sure re. sunday tho)

there is also a nice little bar down from lapad hotel - called the orca, and another one on the other side just up the street.

its right on the water and there is a new part and old part to the hotel, with swimming pool out front.

it would be perfect for one day
