Paid parking options near Garfield?

Am moving to Garfield and 7th-ish next month and will have my car for at least a few months...can't do the alternate side thing due to my schedule so looking for safest, cheapest garage within a 15 minute walk (won't use the car that much). Any suggestions? All help appreciated!

There's a garage on Garfield between 6th and 7th, between Garfield North and the new Slope Jeans. There are also two garages on Union Street between 6th and 7th.

Thanks marble. Strangely, whenever i drive around Park Slope i never seem to see any garages. At least now I know where to look!

And, there is the Methodist Hosptial garage behind the Barnes and Noble building-you could probably get something there also
