downtown grocery store?

lucky us, we will be staying in Los Acos Suites, in beautiful downtown. Can someone tell me the closest grocery store to that area?
Also, do you need Costco membership to shopo at PV Costo?
thanks

Gutierrez Rizo Supermarket is in old town located near the Rio Cuale on Constitución Now...I have not been to it in a couple of years but I am sure it is still there.
I love Los Arcos hotel. Eat a shrimp on a stick for me! Here is a map of all of the supermarkets

foggyYes you need a membership except for drugs. To get there take any Pitallal bus that does NOT say Sams/Walmart. Ask the driver to let you off at Fluvial.
