You can actually do it right at the front desk of your hotel. SL takes a small exchange fee but it's usually not much. Or there is a bank nearby (they'll give you directions). You'll get market rate there, but it's less convenient.

One thing to keep in mind since I have regularly changed $$$ for Colones at the SL Front Desk and that is they tend to have a limit. I believe it's about $200. Could be wrong but that's what I recall. I just mention that in the event you were thing in terms of cashing $500 or $1K etc. A short 5 minute walk up to Ave. Cental and there are boatloads of banks with ATM machines in case you want to use your ATM card to get cash.
